I happened to have an "open" / "empty" Evernight Abbey instance this morning... Thought I'd go in and map the place.
I've run the loc's and attached a SVG and location log file here. I'm not very good at making maps
Also, the inner chamber of the zone wasn't open upon re-entry - so there's a small part not completed. (and I think I doubled up on one part of the map - sorry!)
Hope this helps!
