When the Katar stumbled upon Omak’tiak (home world of the Zedol) they found a planet at war but not over the normal reasons, instead the planet had erupted over two different theories over necromancy. One side believed that Necromancy should be used to steal life essence to empower the spells of necromancy. The other side believed that Summoning undead creatures was the true strength of Necromancy and not life stealing.Seeing a valuable ally, the Katar met with both sides and made an truce with the Zedol. The only condition of the truce was that the Zedol could use ANY dead body for their necromantic purposes.
These creatures are Demonic in nature, have four nasty arms which usually carry heavy plasma weapons.
