Name that Spell

[JJ_Colorado]

Hi,

I am in a game where I keep getting the message:

"Your undead and demonic troops in [ProvinceX] are being struck by holy fire."

What spell am I being hit by? Is it possible to tell? Also I'm neighbors with Pythium, Abysia, and Arco. Which is the most likely candidate?

Thanks for any help.

John

That's not a spell, that a magic site. Some magic sites, including the capitol of non-DF Marignon, can do this. The site works even if undiscovered.
