The Halls of Dwimmermount
Ancient Map of The Borderlands
A tattered and worn scroll of fibrous material, decorated with colored inks.
This map is too tattered to understand easily, but it seems to correspond to Dwimmermount at its exact center. The easily understood symbols seem to correspond to a fort in the north of the wintertops, a fort that could be modern day Adamas, and a mysterious looking installation in the swamp to the northeast.
All of the text is unreadable, being written in the ancient Thulian alphabet.
