The Wrarth Galaxy was a galaxy on the other side of the Universe from Mutter's Spiral.
Galactic law enforcement was handled by the Wrarth Warriors, a biological construct species that answered to the Star Council. The entire galaxy erupted into war when the peaceful Meeps were corrupted by the Black Sun and overran planet after planet until they were finally routed at the Battle of Yarras. (DWM: The Star Beast)
