So, I know that the gnath are probably going to be the next beast tribe quests, but I think that after or along with that, having illuminati beast tribe quests wouldn't be impossible. The story could be something like this: They were with the illuminati. They realize illuminati are bad. They work against the illuminati while acting like they are still with them to sabotage things. They don't go to idyllshire goblins because that would blow their cover. I don't think that goes against any lore.
