User blog comment:Zelron/Soul Stealers in Solstheim (A modest review of The Elder Scrolls V: Dragonborn)/@comment-3025184-20121226015328/@comment-3492791-20121226195917

Daedra often don't look at mortals as more than tools. A Dragonborn would be particularly valuable because, being a direct creation of Akatosh, they probably feel like they are stealing something from the Aedra. Miraak was no longer willing to serve and the Dovahkiin was, so Herma-Mora just sided with the tool that was willing to work.
