(Then I'll just assume the 1/3 joined Setsuna, and became the Darkest Elves. The word Dunmer is now literal!)

The Dunmer that rejected the Ash God and embraced Setsuna's darkness, instantly became more powerful. They saw Mundus clearly, and they considered these 'Mologmer' (Means Fire Elves/People. Closest I could find to Ash Elves. Feel free to make up the name.) invaders to Morrowind. The Dunmer instantly summoned the powers of night, and began their crusade against these invaders. (You never said they left Morrowind, so I'm assuming they're still there.) The Dunmer had decided to crush the Ash Elves, or at least drive them out of Morrowind, for the glory of their new god.

(Odds are the Dunmer are more powerful, while not having as high numbers.)
