Does anybody know where I can find any books or other media that mentions the 13th Founding, its history and perhaps an explanation of how it was achieved, or if anybody already knows this information may I partake of it? Also any references to Tzeentch and any sort of wizard cadre influenced by him. I am hoping to use these idea's for the back story to my chaos lizards, I am working on painting at the moment, and then I will move onto conversions, if anyone has read The Malazan Book Of The Fallen, I intend to base my lizards mutations on K'Chain Che'Malle, any idea's that you have would still be appreciated. Couldn't think of which forum to put it on btw, sorry.
If those stories anywhere, they would be here: http://www.blacklibrary.com/Warhammer-40000/Space-Marines
