Warkeeper
this Yuuzhan Vong creature was bio-engineered to act as a protector and defender of a thrall herder. Resembling a slug and measuring about twenty-two meters in length, the warkeeper was covered with an armored shell that was studded with heavy spikes. These spikes were specially-created plasma emitters, capable of spraying globs of plasma fire at anything with two kilometers of its position. In order to protect the warkeeper, the Yuuzhan Vong also inplanted a dovin basal into the creature's body, allowing it to absorb enemy attacks while it kept the thrall herder free to control its captives. The Yuuzhan Vong warrior commanding the warkeeper had to be constantly vigilant, for this dovin basal could also suck in unsuspecting thralls.
