Heroes' Hole

Description
The caves called Heroes' Hole, located close to the Shrine of Honor, are an expert dungeon filled with loot but also with the worst monsters in existence. Vailiant knights from Serpent's Hold use these caves as a training ground to sharpen their battle skills against real foes. Rumors say, that even an evil Necromancer lives in its depths.

After the time of Ultima VI, there Heroes' Hole vanished, to be never heard of again. It is unknown if the complete collapse of the Realm of the Gargoyles destroyed it.
