I am a huge fan of the Warhammer universe and I ' m not at a computer right now but I can give you a general run down for his character Tzeentchs title is the Lord of Change . He is absolutely a solid choice for great old one , since he is one of the gods of chaos in that universe . Tzeentchs followers often display strange mutations and warped intelligence . Tzeentch is a plotter . He schemes and manipulates people , even the other chaos gods . His number one job is to break the status quo . Never let things stagnate . Incite war between nations , or maybe peace between angry neighbors , all to accomplish some nebulous plan that may come to fruition years from now . EDIT on consideration , I thought I should mention how important this is . He doesn ' t do only evil or good , though his ultimate goal is chaos , he will often help heroes and do good things even if it hinders him because Tzeentch HATES for things to stay the same , and any change is better than no change . He wants to flip things on their head and break people ' s sanity by making them convinced that the world is unquestionably chaotic in nature . He often rewards followers that successfully aid his schemes , or come up with and accomplish their own , with secret magics , warping their bodies to grant them new powers like wings or more eyesmouths , or the location of items . This is usually just to help him however . He doesn ' t consider his followers any more valuable than a chess player would consider a rook or a bishop over a pawn , and uses them as much as they use him for power .
