Well, it came up on the Sage Tower, so I thought I'd finish up my writeup right quick and post it. For the uninitiated, Trothyr's Rest is a nice dungeon with easily-dispatchable singly-encountered (for the most part) Liches, with an occasional Azure Gromnie thrown in. The quest items are rather ho-hum; still, the nice interior architecture makes this a fun place.
Additionally, in the deepest bowels of the dungeon lies the Altar of Asheron.
