Mother Queen

The Mother Queen was a member of the urnsor'is species and the source of the species' infestation within the Myyydril Caverns on the Wookiee homeworld of Kashyyyk during the Galactic Civil War in 1.5 ABY. Chief Kallaarac and nurse Yraka Nes of the Myyydril tribe both wished the creature's death. Yraka needed a special healing salve that came only from the Queen, and Kallaarac wished the beast destroyed so that the tribe could finally live in peace. The spacer they contracted to perform the deed for them was successful in slaying the foul parasite. Kallaarac rewarded the spacer with unique sword named Urnsor'is SoulLeecher, and Yraka compensated them with a cybernetic arm. The arm was equipped with a special module used to revive a comrade in the field who was near death.
