The Urnsor'is SoulLeecher was a unique one-handed sword made from some unknown part of the vicious urnsor'is creatures of the Myyydril Caverns on the Wookiee world of Kashyyyk. It was created by the Myyydril tribe who lived in the caverns. It was gifted to a spacer by Chief Kallaarac after the spacer killed an especially ferocious Urnsor'is known as "Mother Queen."
