Ok, death magic and afflictions, what's the deal?

It was a G1 scale.

There was a D3 domain nearby, but at the turn I saw it, the province in which my character was was at Growth1. So at most it could have been at 0 scales for either side.

It IS possible that I might have stepped into a high death province without noticing, or suffered a battle affliction before that (couldnt be on that turn or the previous one, though. Provinces fell without opposition). I know it can't be one of the "spreads disease" sites because I think they are all death, and I was making my D4 wizard search every province (so he'd have noticed)
