Wurm

Wurms were a race of vicious conquerors.

Biology
Wurms looked like giant earthworms the size of baby elephants. They had no distinct features other than stubby arms. Wurms could spit out an acidic, dark liquid out of the heads for defence. They leaked a fluid like wallpaper paste when injured. They were able to hunt by smell and by vibrations in the ground. Wurms were able to reproduce by the hundreds independently.

Technology
Wurm spaceships were biological in origin and were adapted from living organisms. They were large, segmented ships. A Wurm spaceship could shoot out mud, which was used to cushion the landing andto provide a medium for the Wurms to move through. The ships were also filled with mud to allow the Wurms to move around. The controls looked like tree-roots and the screens were made of sacks of webbing.

Wurms used guns which were surgically attached to their arms, which shot out clods of dirt. Inside this dirt were colonies of genetically modified insects that could eat the guardians created by Valnaxi treasure troves. Wurms wore white, plated armour and helmets. Wurms had cybernetic implants to improve their bodies and senses. (NSA: The Art of Destruction)


 * Presumably, the Wurms used different weaponry when they were fighting different species.

History
The Wurms came into conflict with the Valnaxi, since they controlled a planet which could either be added to the empire or used as a bridgehead for an invasion into Wurm space. They fought with them over 17 star systems, though by the year 118, the Valnaxi had lost the war.

The Wurms didn't leave their victory at that, and also set out to destroy all of the Valnaxi's artwork. It took them 2000 years to find all of the hidden treasure troves of the Valnaxi. In 2118, a group of Wurms led by King Ottak and Knight-Major Korr went in search of what they believed to be the last of the Valnaxi treasure troves. (NSA: The Art of Destruction)
