Assanti was once a demon worshipped by the kuo-toa, until the tribe that worshipped him was slaughtered and the demon was captured by a powerful drow wizard. The demon is said to reside in this weapon, which was made for the wizard's pet, a drider named Harahasha. When the wizard's clan was destroyed by a rival family, the weapon was lost in an earthquake that engulfed the wizard's home.
