Only when on the Nothing You Can Possess quest is it possible to get past the door on the first floor, as it requires a key. When past the door/wall there are only undead enemies.
Be aware of the shooting Dark Welkynd Stones on the first level as they are powerful and can drain health quickly. There is a floor trap further through on the second level.

Umbacano has asked the Hero to retrieve a carved panel from an Ayleid site known only as the High Fane in his sources. He has given them a sketch which will help to identify this ruin, as well as one of the carving which he wants. He also gave them a carved stone key which will allow them to enter the central chamber of the High Fane when finding it.
