There are certain objects in the world known as "Relics".
No, not like articles of fine art or antiques. They're magic tools created by powerful magicians and mighty ancients, or objects that gained power after long exposure to their owner's grudges and natural spiritual power—many "cursed items' were often times, in fact, Relics.
They appear in old stories, anecdotes, or legends as "objects of power".
For example: a stone that brings good luck, a doll whose hair grows night after night, a mirror that shows you how you'll look in the future, or a sword that brings ruin to anyone who draws it.
Most everyone has heard of stories like that.
People often consider Relics to be mere fantasies because they've never come across any. Even if a relic were right before their eyes, they'd fail to notice it. If a mysterious event were to occur, they'd just dismiss it as a coincidence.
Some simply don't care, while others are certain that such things do not exist.
But Relics are real, and more common than people think.
Whether they bring about good or ill fortune depends on the ones who choose to use them.
