I'm kind of surprised that there hasn't been any (Known) Ascian meddling at the steppe yet, honestly.

The Xaela seem like a people who could easily be manipulated into summoning a primal with many of them having a belief in gods, along with the constant tribal conflict and imbalance of power amongst them providing a reason for it.

I suppose the lower aether levels in Othard might make such a thing difficullt, though.
