Just want to let others know that the whole forlorn set can and did drop from the undead guardsman room with the forgotten promise, where I just completed my set. Other than the fact that the mobs call for help, it was the most comfortable place to farm for the set for me a level 14 cleric. The leggings and hauberk dropped from the ones back behind the forgotten promise. Not sure if that is just a coincidence or not.
I also encountered an Ancient Helm of the Forlorn, which is not found in the item database.
