Corpol

Corpol is an object mostly mentioned in the book Orphans' Adventures: The Lost City. Corpol is a granite-like stone that is the main symbol of the Dark Side.

In the early 1900s, the Dark Side found the rock in the basilisk chamber of the brownstone dungeon of theirs. They had no clue what the rock was or where it came from, so they used it for their own good. They carved DARK on the original Corpol stone.
