Lore wise, whats to stop theoretically a bunch of summoners getting together and summoning a larger Egi or something similiar to a Primal? I thought Primals came into existance via a combination of Aether and concentrated "worship" or sorts, so why can Beastmen do it and not Summoners? I guess what I am getting at is, say if you have two summoners in a party, why can't they combine their powers to summon a larger primal being?
