Soldevan wants to open up a pathway to the warp and seek out the consciousnesses that dwell there hoping to bargain with them for the power he needs to combat the enemies of mankind. Soldevan has got quite close to his goal and has several forbidden tomes in his possession that, with the right sacrifices and rituals, will summon forth powerful Daemons for him to negotiate with. He is always seeking more knowledge or artefacts of the warp, either captured during the cabal’s operations or purchased at extortionate prices from unscrupulous dealers in forbidden relics. Somewhere during this process Soldevan has lost his sanity and replaced it with absolute conviction that the warp holds the secrets of humanity’s survival. He believes that the Tyrant Star represents a vital conduit to secrets of the warp.
Among other things, he is known for slaying the psi-abomination of the Bloodmind on war-torn Malice.
