Well, Enweil certainly /did/ ally with the daimons...and Enweil was both getting ready to attack a human realm and gave its support to Fronen/Bara'Khur when they did. Their reason was 'stop attacking the daimons or we will kill you'.
I admit that the points of distinction between Enweilian alliances and Sint's during the last invasion are a bit too fine for me to allow to call for the destruction of one realm and the view of the other as potential saviour....
