That point aside unless it was some very specific magic administered over enough time that they would know what was happening then this sort of thing had to be caused by demonic magic. However twisted the demons are they don't do things without a reason. Most of the time the things they do are for food or enjoyment. There is no reason why they'd give a set of warriors more powerful bodies without proceeding to slaughter them very slowly and painfully afterwards. This transformation more or less allowed the warriors to take control of a good portion of the country side. Demons don't give out that kind of power for no reason.

I'm trying to offer a compromise in that the magic that caused the curse was not of demonic origin, as that already seemed not to fly with Vladimir, given the constraints of the setting. Is there really any reason to assume it couldn't have been another source? Who says it "had to be caused by demonic magic?" Unless specified elsewhere, magic is often very vague and open to interpretation, and I'm assuming it's so here. Whatever consensus I come to with the GMs, I'll have to rework my history, and I'm figuring out what can and can't work in the realm of the setting.
