The Hand of Bane was an artifact created by the priesthood of Bane to enable Bane to be resurrected, should the need arise.
The hand was hidden in the city of Sigil, in a former temple to Bane.
The hand was carved from black obsidian, about the size of an ogre's paw. The fingers were curled upwards, with fingernails of red garnet. The hand is also studded with diamonds, giving it a poxy appearance.
