We don't know what the conditions of Tatseni's treaty with Erosia were, but they did have a treaty and likely provided some kind of service to Erosia that made it more convienient to leave them free than conquer them. We have no reason to believe they had similar arrangements with rodak, Stenai, or Ghenalon though.
