A small monastery in the forest of Beforet, ruled by King Iweret.
The monks at the Sorrowful Fief disapproved of Iweret’s murderous activities, but they could not deny that the wealth taken from the corpses of warriors slain by Iweret kept the monastery busy and prosperous. Lancelot lodged in the Sorrowful Fief before he fought Iweret in combat.
