I recently finished this map through an Altar victory with the Kuriotates. Didn't really pay much attention to what happened outside my little island, because I'd already decided to play a defensive game, and the kuriotates were perfect for that, especially because I was never attacked, due to the AI not understanding naval warfare very well.
One thing I did notice, though, was that in the early game, the Clan was completely conquered by the Hippus, leading them to being the scorer throughout the whole game, and apparently gave them so much excess research that they founded Empyrean, and became leader of the Overcouncil, also until the end of the game.
One other thing that I noticed, but wasn't surprised about, was that Khazad conquered most of Luchuirp, but that's been happening in every single game I've played that they both were in, scenario or not. Guess they just don't like each other.
