I tried out the Gift of Kurgi ritual in an SP game a couple weeks ago, and it seemed to be working OK. The trick was, the horror only attacked enemy provinces that contained enemy units (PD didn't count), and it only functioned as a killing machine, not as an occupier (meaning, even if it single-handedly won the battle, the province still remained in enemy hands). When I sent it against "empty" provinces (again PD alone didn't count), nothing happened.

Think of it more as a ritual that attacks enemy units only, like Fires from Afar (although one that lets you watch a battle), but not an "airborne attack" spell like Call of the Wild or Call of the Winds.
