Astorthas[1]
Astorthas the Inconstant is a Thousand Sons Exalted Sorcerer of the Cult of Mutation[1].
The only immutable property of Astorthas is his armour, which he relies upon to keep his physical presence in a functioning, cohesive state. His body, voice and even thought processes are in a constant state of flux while his stave ejects a warping biomass that turns those touched by it into a new member of his Chaos Spawn pack.[1]
