Ivory is an enchanted long-knife also known as 'The Sword of the Planes'.
Appearance and Magical Properties
The pure white knife Ivory has several magical abilities, all centered toward the dispelling and killing of extraplanar creatures. While the blade is always sharpened and ready to cut to meat and bone, it has been granted abilities that enable it to do more harm to extraplanar creatures than it would to normal beings. When cutting into Elementals, natives of the astral plane or Outsiders, Ivory is far more lethal and produces a 'crackle' sound on contact with them.
Ivory has a curved golden handle, with intricate designs of Archdevils running down the hilt, and a large gem at the pommel. The blade itself is pure white.
The knife Ivory was forged by the assassin William Listakian when he was trapped in the basements of the Drow who imprisoned him for over a decade. This knife, as well as it's counterpart Ebony are the only two pieces of equipment that have been carried about by the man ever since he was released into daylight. Initially just a normal weapon, they were imbued with magical power after the assassin was ambushed by extraplanar lions summoned by the mage Cherub Vassago
