The Eerie Glade is a hidden location on the wilderness map, found to the north of the Mad Minstrel's Clearing. It is revealed on the wilderness map by first talking to Thrundarr about Rolf, and then talking to the grizzled dwarven veteran twice.
The glade features several dwarven graves, along with a single special grave. Digging up the special grave yields a truesilver cap, a truesilver chain mail, a medium truesilver shield, an amulet of perseverance, a broken truesilver battle axe, an ancient dwarven key, and an antediluvian scroll covered with dwarven runes. The key is needed for part of the Rolf quest. Digging up the other graves will occasionally yield some random treasure, in addition to producing a hostile dwarven battle spirit.
