Death may be shitty but it's also very thematic pick as well. Plus some feat choices and PrC's would get locked out if you do not have way access death domain (as it can be prerequisite for some PrC's which would be thematic for cultists). But I agree you should pick between Undead or Undeath (one for spells in general and other for better ability).<br/><br/>Deathbound is good pick but so can be the sin domains (pride, wrath, envy, gluttony, greed, sloth, lust) as mentioned by Pale. Or simply Magic (for just any magic than necromancy) and Trickery (the fey side Anasil has).<br/><br/>Pale; I haven't got time listen the themes yet....were they in PM?
