We've been bugged. It's skyhopper season in the lowlands, which means the pests are everywhere. One of the High Order mages reported that one of the insects that they killed had an enchantment of some kind placed upon it. When we inspected it closely it seems to be some sort of listening spell. We suspect that the cult is using these enchanted insects as spies. Go and exterminate them for us. You won't be able to tell which are enchanted by looking at them, so you'll just have to kill them all.
