Been digging up info on lake rathe gnolls, as I remember them being different than they are now. I believe the gnolls that are currently there were put in during Luclin, but I can't find any info on an exact time.
I think all of the gnolls there spawned as the white model, like the escaped splitpaw gnolls in South Karana, and carried the same faction hits. Pictures from these links help confirm it. Currently all that I can find though.
