Re-reading the last episode... the evil guys are called "Vullii" there and back in Issue 2 - "Vulii"...one of those two is a typo, and I am pretty sure it's the second one.
Just though I might share

Yeah, I noticed that too. Though I can't say which is the typo, you would have to look back on it. I was thinking "vullii" is the typo though I dont' know for sure.

Maybe Vullii is the area and Vulii are the people.
