It is usually that instantly thing. Vikings try really hard to avoid dying from wounds after a battle. No one wants to pass up on Valhalla, so you need to die in battle or not at all.

Leads to a lot of amputations to avoid dying from infection, but if we had better medicine, there could at least be less of that. Not that its always avoidable, but not every limb gets half chomped off by a dragon.

You're from Caeli's world. There is some....real wild things there. Magic. Gods you talk to. Also your dragons are this amazing magic thing that is still really weird to hear about. So I could see it as being possible there.

How much do you have to go?
