There is a reference I recall to a dog and maybe rat-like race being seen on an Akaviri pirate ship or something. I cannot find it and it is driving me nuts. Anyone have the source?

Someone found it for me; I should have known it was in PGE: http://www.uesp.net/wiki/Lore:Pocket_Guide_to_the_Empire,_3rd_Edition/Other_Lands

Relevant line: "Contemporary scholars find references to pirates with rat-like features, and still others who appeared canine, suggesting Akaviri cultures yet undiscovered and perhaps extinct."
