"I'll take coffee." Oilcan settled near to Tinker, fidgeting. "How long will the tests take?"

Lain shot a glance toward Pony standing guard by the door. "It's against the treaty to do gene scans of elves."

"I'm not an elf," Tinker growled, and dunked one of the strawberries.

"I know," Lain murmured. "But we can't let your guard know what we're doing."

Tinker controlled the urge to glance toward Pony. "Ah. Yes." She nibbled at the strawberry, considering. "Well, he seems to do what I tell him to do."

Oilcan also studiously avoided looking at Pony. "If we station him at the front door, then we can be in the lab unwatched."

So Tinker finished her strawberries, moved Pony to the foyer, and went back to the lab to have her blood drawn.

"When we're done, I'm going to destroy the samples and the results." Lain tied a tourniquet around Tinker's arm and swabbed down a patch of skin inside her elbow with alcohol. "It's a whole little Pandora's box we're peeking into. You will not tell anyone-not humans or elves-about this."

"We won't," Tinker promised.

Oilcan echoed it, and then added, "It's just for us to know."

Lain not only took a blood sample from Tinker, but also swabbed the inside of Tinker's mouth, plunked out a hair, and then asked for a stool sample.

"What?" Tinker cried. "Why?"

"Please, Tinker, don't be squeamish." Lain motioned Oilcan to sit in the chair Tinker just vacated. "The cells of the intestinal lining are excreted with the stool and are a source of DNA. I want to see how invasive this change is."

Lain was just untying the tourniquet on Oilcan's arm when the doorbell rang.

"Oh, who can that be?" Lain grumbled. She put the vials containing the blood out of sight, and stuck a bandage on Oilcan's arm. "Pull your sleeve down, Tink."

The woman on the front porch looked familiar. She brightened at the sight of Tinker and said to Oilcan, "Oh, wow, you found your cousin!"

"Yeah." Oilcan actually looked sheepish under Tinker's puzzled stare. "You remember Ryan. She's one of the astronomers?"

Oh yes, the one she'd tried to warn off the night of the cookout.

"I came over to see if there was any news." Ryan waved toward the Observatory. "I'm just getting done for the night, and I thought I'd check in before hitting..." She stopped and c.o.c.ked her head. "You weren't always an elf, were you?"

"I've got work to do," Lain announced into the sudden silence.

"No, no! She-she-" Oilcan looked to Tinker for help.

"Don't look at me," Tinker snapped, then picked up on Lain's cue. "I want to go to Tooloo's to stock up on some food I can actually eat. Do you want anything, Lain?"

"Actually, yes. See what she has in the way of fish. A dozen eggs." Lain listed her needs as she crutched to the kitchen and returned with her shopping basket and a gla.s.s milk bottle that she held out to Tinker. "A pint of whipping cream. And some fresh bread would be nice."

Tinker took the empty return and wicker basket. "I'll be back in...two hours?"

Lain nodded. "That would be good."

That left Ryan to be kept out from under Lain's feet. Oilcan blushed slightly at his a.s.signment, but indicated the dorms with a jerk of his head. "Let me walk you back to the dorms, Ryan, and I'll explain."

So they split up, each to their own task.

Pony insisted that Tinker sit in the back of the Rolls, so she hung over the front seat to give him directions to Tooloo's store. She noticed that he handled the car smoothly as he took it down the sharply curving hill of the Observatory.

"How long have you been driving driving?" Driving was an English word, since the nearest Elvish words implied horses and reins.

"Nae hae." No years. The full saying was Kaetat nae hae, Kaetat nae hae, literally "Count no years" but actually meant "too many years to count"-a common expression among elves; it could mean as few as ten years or as many as a thousand. After a thousand, it changed to literally "Count no years" but actually meant "too many years to count"-a common expression among elves; it could mean as few as ten years or as many as a thousand. After a thousand, it changed to Nae hou Nae hou, or roughly, "too many millennia to count." In this case, however, Nae hae Nae hae had to be less than twenty years, since that was when the elves were introduced to modern technology with Pittsburgh's arrival. had to be less than twenty years, since that was when the elves were introduced to modern technology with Pittsburgh's arrival.

"The Rolls were part of the treaty," Pony explained. "It required that the EIA provide quality cars for ze domou ani ze domou ani's use. All of his guard learned, as did husepavua husepavua and and ze domou ani ze domou ani, though not all enjoy doing it."

"Do you?"

"Very much. Domou Domou lets me race, although lets me race, although husepavua husepavua says it is reckless." says it is reckless."

She directed him onto the McKees Rocks Bridge. The morning sun was dazzling on the river below. "Who is husepavua husepavua?"

"Lifted Sparrow By Wind."

The name sounded familiar, but it took her a moment to place it; Sparrow had been the stunningly beautiful high-caste elf at the hospice. Pony had mentioned her once or twice the night before, calling her just Sparrow.

"Is Sparrow...Windwolf's wife?"

He looked at her with utter surprise on his face, reinforcing her impression that he was fairly young. "No, domi domi! They are not even lovers."

Oh, good. Pony was giving her amazingly direct answers, something she hadn't thought possible for elves. Perhaps it had to do with his willingness to obey her-had Windwolf told him to do so? Or was it an offshoot of being young? "How old are you, Pony?"

"I turned a hundred this year."

While that seemed really old to her, she knew that elves didn't start into p.u.b.erty until their late twenties and weren't considered adults until their hundredth birthday. In a weird, twisted way, she and Pony were age-equals, although she suspected that he was much more experienced than she could hope to be.

"Is this the place?" Pony asked, pulling to a stop beside Tooloo's seedy storefront. To conserve heat in the winter, the old half-elf had replaced the plate gla.s.s with salvaged gla.s.s blocks. Somehow, though, she'd tinted the blocks, so the wall of gla.s.s became a stained-gla.s.s mosaic on a six-inch-square scale. Typical of elfin artwork, the picture was too large for a human to easily grasp. If one stood in the kitchenette and looked through the entire length of the shop, one could see that the squares formed a tree branch, sun shafting through the leaves, with the swell of a ripe apple dangling underneath. From the outside, though, one only saw the salvaged block and the muted colors in a seemingly random pattern-keeping the store's secrets just as the storekeeper kept hers.

The only nod toward advertising the store's function was painted under the length of the windows: Bread, b.u.t.ter, Eggs, Fish, Fowl, Honey, Pittsburgh Internet Access, Milk, Spellcasting, Telephone, Translations, Video Rentals. Of the words that could be translated into Elvish, the rune followed the English word. It mattered much to Tinker that she could remember standing in hot summer sun as the cicadas droned loudly, carefully painting in the English traced onto the wall by Tooloo's graceful hand.

"Yes, this is it." Tinker slid out.

She hadn't considered Tooloo's reaction to her transformation. When the old half-elf saw her, Tooloo let out a banshee cry and caught Tinker by both ears. "Look at what that monster did to my dear little wee one! He's killed you."

"Ow! Ow! Stop that!" Tinker smacked Tooloo's hands away. "That hurt! And I'm not dead."

"My wee one was human, growing up in a flash of quicksilver. Dirty Skin Clan sc.u.m." Tooloo spat.

"Windwolf is Wind Clan." Tinker rubbed the soreness from her ears.

"All domana domana are Skin Clan b.a.s.t.a.r.ds," Tooloo snapped. are Skin Clan b.a.s.t.a.r.ds," Tooloo snapped.

Tinker winced and glanced to Pony. Thankfully, the exchange had been in English, but Pony obviously had picked up Windwolf's name and was listening intently. "Don't insult him, Tooloo. Besides, if you'd just warned me, I might have been able to avoid this."

"I told you the fire was hot! I told you that it burns! I told you to be careful. So don't cry that I never told you it could burn down the house. I warned you that Windwolf would be the end of you, and see, I told you and there it is."

"You have told me nothing." She went and got a basket, angry now but determined to keep her calm. "Knowledge is not cryptic warnings, indistinguishable from utter nonsense. 'All domana domana are Skin Clan b.a.s.t.a.r.ds.' What the h.e.l.l does that mean? I've never heard of the Skin Clan." are Skin Clan b.a.s.t.a.r.ds.' What the h.e.l.l does that mean? I've never heard of the Skin Clan."

"There wasn't a need for you to know if you'd just stayed away from Windwolf. I know humans; if it's ancient history, it doesn't pertain, so I would have been wasting breath to explain a war that happened before the fall of Babylon."

Tinker picked up a crock of honey, intending to put it into her basket. "Well, tell me now."

"Too late now." Tooloo stalked away, flapping her hands over her head as if to swat away questions. "Done is done!"

Tinker barely refrained from flinging the crock at Tooloo's retreating backside. "Tooloo, for once just tell me, d.a.m.n it! Who knows what mess I might get into because you've kept me ignorant?"

Tooloo scowled at her. "I have things to do. Cows to milk. Chickens to feed. Eggs to gather."

"Well, you don't feed chickens with your mouth. I'll help you, and you can tell me what I need to know." Besides, Tinker had to keep Pony out from under Lain's feet for a full two hours.

Tooloo sulked but went to the store's front door, flipped the "Open" sign to "Closed" and threw the dead bolt, muttering all the while.

Tooloo lived in the one big back room of the store, a house done at miniature scale with changes in the flooring to indicate where walls should be. Mosaic tile delineated the kitchenette. The two wing chairs of the living room sat on gleaming cherry-wood planks. The floor around Tooloo's fantastically odd bed was strewn with warg skins. Tinker had spent countless hours on the floor, from studying the dragon shown coiled on the kitchenette's tile to building forts under the bed. She thought she knew it well.

Entering the room, Tinker discovered she didn't know it completely.

It felt like stepping into a pool of invisible warmth. No. There was movement, a slow current to it, heading east to west. She stopped, surprised, looking down at the wood. It did more than gleam. It shimmered as if heat roiled the air between her toes and her eyes. As she studied the floor, an odd, pleasant sensation crept up her legs until her whole body felt strangely light.

Even odder was the change in Tooloo's bed. The pale yellow wood seemed at once sharper and brighter, almost surreal, like someone had overlain computer graphics onto reality.

Pony followed Tinker's gaze, and grunted in surprise. "Dragon bones."

"Yes, dragon bones," Tooloo snapped, wrapping her braid loosely around her neck like a scarf of thick, silver cording. "That's how I survived on Earth all these centuries. Silly beast died without the magic, but its very bones stored ma.s.sive amounts that slowly leaked off. Every night I slept in that bed, nae hou nae hou, aging only when I strayed away from it. I was tempted to burn it after the Pathway reopened, but waste not, want not, as the humans say. There were times I grew so depressed that I wouldn't stir out of it for months on end."

"Why is the floor so weird?" Tinker asked Tooloo, but the half-elf had stepped out the back, so she turned instead to Pony. "Can you feel that?"

"It must be a ley line."

"I can see see it-I think." it-I think."

"Yes, you should be able to." But he explained no further.

Deciding to focus on one mystery at a time, Tinker went out into the backyard after Tooloo. What used to be a small public park lay behind the store, but Tooloo had claimed every patch of green in the area plus several nearby buildings to use as barns, regardless of what their previous functions might have been. Fenced and warded, her small yard gave way to a sprawling barnyard.

Tooloo had already filled a pan with cracked corn from the feed room and now stood throwing out handfuls, calling, "Chick, chick, chick." All the barnyard fowl ran toward the falling kernels. She kept a mix of Rhode Island Reds (which were good egg layers), little bantams (which fared better on the edge of Elfhome's wilderness), and a mated pair of gray geese called Yin and Yang (that acted more like watchdogs than birds).

"Tell me about the Skin Clan." Tinker picked her way through the pecking and scratching birds. Pony hung back, staring in fascination at the chickens. She wondered if elves had chickens, or if they were one of the species that hadn't developed on Elfhome.

"Tens of thousands of years ago, in a time past reckoning, the first of our race discovered magic." Tooloo tossed out handfuls of corn. "It is said that we were tribes then, nomadic hunters. Our myths and legends claim that the G.o.ds gave magic first to the tribe that became the Fire Clan, and perhaps that is true. It is fairly simple to twist magic into flame.

"But one tribe rose up and enslaved all the rest-they were the ones who practiced skin magic. They learned how to use magic to warp flesh, and to remake creatures stronger and faster. They were the ones who discovered immortality, and they used the beginning of their long lives to make themselves G.o.dlike in beauty, grace, and form."

Tinker scooped out handfuls of corn and flung it at the chickens to speed up the feeding process. "I don't understand how they enslaved the others; surely not because they were pretty."

"Can you imagine the advances that your famous thinkers might have made if they had lived a thousand years? What would Einstein be creating if he were still alive today? Or what Aristotle, da Vinci, Newton, Einstein, and Hawking could create if they all worked together."

"Wow."

"As a race, we went from being bands of nomadic hunters to an empire with cities in a fraction of the time it took humans. As their realm expanded, the Skin Clan crafted fierce beasts to wage war and enforce their laws: the dragons, the wyverns, the wargs, and many other monstrous creatures. In time, they spanned the known world, which was roughly Europe, Asia, and Africa on Earth.

"All of this happened before humans dreamed of building their first mud hut." Tooloo dumped the last of the corn, tapping the fine dust and small bits of broken kernels out to be fought over by the chickens. "See, old news."

Exchanging the feed pail for wicker baskets, Tooloo headed for the one-car garage converted into a chicken coop. Long used to helping Tooloo with ch.o.r.es, Tinker took one of the baskets and worked the east wall of cubbyholes, lifting the day's eggs out of the still-warm nests. It was easy to tell which nest belonged to the bantams, as the eggs were much smaller. Pony stepped cautiously into the coop, peered into one of the cubbyholes near the door, and lifted out an egg, which he examined closely.

"Okay." Tinker carefully deposited her discoveries into her basket. "But there's some reason you're telling me about the Skin Clan."

"They are the seed of everything elfin." Tooloo systematically worked through the western cubbyholes. "Human are like snowflakes; nothing about humans is the same. They've chopped their planet up into thousands of governments, cultures, traditions, religions, so forth and so on. At their dawn, though, the elves were all gathered together and forced into the same mold and then made immortal. As we were when the humans started to build the pyramids, we are still."

Windwolf had talked about the stagnation of his race, but Tinker hadn't realized that it was so profound.

"Why haven't I heard of the Skin Clan before?"

"Because they're all dead, except for their b.a.s.t.a.r.d children, the domana domana."

"What happened? How did they die?"

"They didn't die, silly thing; they were killed. Hunted down. Killed to the last one-in theory."

With that Tooloo ducked out of the coop and swung around to her back door to set her basket in the store before heading for the small milk barn.

"Wait!" Tinker s.n.a.t.c.hed up the last of the eggs, including the one Pony still held, and scurried after Tooloo. She caught up to her at the pasture where Tooloo's four milk cows waited to be let out. "Tooloo!"

"What?" Tooloo opened the pasture gate and the cows ambled to their stalls without guidance. "I'm trying to compress twenty thousand years of history into a teaspoon, and you complain? History isn't easy stuff. It's a tangled web full of lies and deceit. There's no easy way of pouring it out."

"Okay, fine, the domana domana are the Skin Clan's children?" are the Skin Clan's children?"

Tooloo scoffed loudly as she poured grain out to the cows. "The Skin Clan was the first of the castes, for they raised themselves up to perfection. Then they created the other castes. The filintau filintau born for a clean breeding stock. The born for a clean breeding stock. The sekasha sekasha." Tooloo thumped Pony in the chest. "Sound and strong, able to withstand ma.s.sive damage, but not necessarily smart. It's the same that humans did with dogs, chickens, and cows." She gave one of the cows a similar pat. "Breed a bloodline for certain properties until they're nearly a different species-and when they no longer suit, let them die off. When I lived in Ireland, I had this lovely herd of small, hardy Kerry cows that nearly went the way of the quagga."

"The what?"

"It was like a zebra. It went extinct in the days of Queen Victoria. Ah, there was a woman!"

"So, the Skin Clan set up the castes and fathered the domana domana?" Tinker tried to steer the conversation back to elfin history.

"As you will no doubt learn, you don't wake up and fully realize you're immortal. It takes a few hundred years." Tooloo washed her hands, took down a clean milk bucket, and moved the milk stool beside the first cow. "Once the genetic tinkering started, the Skin Clan grew increasingly infertile, so they originally accepted all their offspring into the caste. About a thousand years into their immortality, they realized that they were diluting their power by sharing it with their 'half-breed' children, so they ruled that only those born to a Skin Clan female could be accepted into the caste. It did not keep the males, however, from fathering children among the lower castes, and that's where the domana domana came from." came from."

Tinker leaned against the stall side, watching Tooloo wipe the udder clean and position the milk bucket. Tinker drew a line at milking the cows, as she'd been swatted in the face with a tail once too often. Pony watched in complete mystification. Head tucked against the cow's flank, Tooloo settled into a fast milking rhythm, shooting alternating streams of milk into the bucket. "This happened a long time ago; Windwolf wasn't even born. And even if his father is a Skin Clan b.a.s.t.a.r.d, so what? Oilcan's father killed his mother, and that doesn't make Oilcan a bad person."

"Nah, nah, Longwind-Windwolf's father-is just a young buck too. Politics does what time can't; Windwolf's grandfather, Howling, was murdered and Longwind took his place as clan head. Howling, though, he was ten thousand years old when the blade found him, and he had been part of the Skin Clan downfall. But to be precise, he wasn't the b.a.s.t.a.r.d-it was his father, Quick Blade, before him, who was the b.a.s.t.a.r.d, but Quick Blade died in battle during the war."

"How do you know all this?"
