From Lord Kyre:
Kyre chose the serpent as his Kabal's namesake due to their stealthy and deadly nature, a fact he studied closely on the death world of Guleam. As a young, up-and-coming Dracon, Kyre found himself stranded on the death world with his fellow soldiers. The giant serpents that called the world home were able to strike without warning, slaughtering most of his warriors within a day. Only by utilising his cunning and skills did he survive, claiming the skull of one of the giant beasts for his own personal totem.
