Canon:Sword of Kas

In the World of Greyhawk campaign setting for the Dungeons & Dragons role-playing game, the Sword of Kas was the mighty blade used by Kas the Bloody-Handed, the dreaded lieutenant of Vecna. It was by this blade, some say, that Vecna lost his Hand and Eye.

The sword, variously described as a short sword, longsword, or greatsword, was crafted by Vecna. The blade is said to have been magically honed to a razor's edge, enhanced the wielder's strength, and could be used to call down lightning bolts from any storm clouds that might be overhead. The sword itself is intelligent, possessing a vile and murderous spirit.

Publication History
The Sword of Kas first appeared in the Original D&D supplement, Eldritich Wizardry. It was one of the first artifacts detailed for the Dungeons & Dragons game. The sword has been updated many times and has even been the object of quests as in the adventure Vecna Lives.
