Warhammer 40k: SPACE RATS

Last semester's Warhammer 40k class took a race that existed in regular, fantasy Warhammer, and brought it into the 41st millennium.  The reasoning behind this was to use many of the preexisting units, and just upgrade them, i.e., half the work is already done.  So I decided to take a similar approach.

The Skaven are a race of verminous rats that spread out and take over urban areas, basically, smart rats.  So the bulk of the idea was to just bring this race into Warhammer 40k.  Though, since I'm not to keen on every race being grimdark, I'm changing the Skaven to a more peaceful race, or at least peaceful by Warhammer 40k standards.  Before humanity descended into ultra religious dogma, they roamed the galaxy as explorers, so the lore of my Skaven are that rats stowed away on board, and gradually evolved alongside humans.  Now, they're a heavily expansionist race that see themselves as the proper successors to mankind.
