Meh...the Rats are supposed to be an initiation quest for the Fighters guild lol. Or in Skyrims case it should have been the Companions I guess. The Honningbrew meadery wasn't about clearing out rats though iirc was it? Wasnt it poison or something?
Companions =/= FG. Completely different organization and technically the Companions aren't a guild, just a band of mercenaries with no actual ranking system.
as always the Daedra should remain a part of the TES series, they are a very important thing as well as natural creatures like rats, wolves, bears etc etc or just have wildlife thats exotic i.e. Morrowind's nix-hounds, alit, guar
