Forename, while you were assisting our scouts to the northeast, two locations were discovered to the west that appear to be ancient battlefields. I think these would be ideal places to take aetheric measurements.
I've sent scouts to each location already, but the ever-present threat of attack makes it difficult for them to obtain accurate readings. Please, Forename, ensure their safety whilst they perform their duties.
Head to Sothton Walls first, and meet with my scout. He'll let you know what's required of you.
