I didn't add Elementals because they already exist in the game as summonable creatures, and that role suits them perfectly. Yes, I really liked their castle, but it's too late to change anything now. By the way, judging by the beauty inside the castle, the Swamp faction could have a very beautiful castle. And other factions could also have quite impressive castles... I'm just puzzled by Nival's behavior – in the racial contest, they chose far from the best participants. But I think they simply have to create Barbarians or Swamp creatures for us : )
