Clan Pestilence it is then.
Last page of the ebook it speaks of a twin-tailed comet. In the Rise of Sotek wiki, ctrl+f "Comet" and you should find the relevance. Guess the Lizardmen are going to get something like Dark Elf Hydra. Which means the Skaven might get a Verminlord (Corruptor, cus they are Pestilence)?
