I'm going to go with Trifletraxor on this one...need spoonfeeding.
As far as the non-crunchy bits go, the Cova seem pretty cool...I get the impression they look a bit like Shuma-Gorath (for some reason
) though you don't describe them that way...and way more cool than a space cat!
As for Skaven in space...oh yeah! Of course when you show up at the WH table with your Necron/Vampire Counts...you get odd looks...although High Tech Skaven (modded off orks??) would get some odd looks too...Bah!
