This area is accessed in limited form from the Watcher's Keep Final Seal dungeon level within Watcher's Keep, during Baldur's Gate II: Enhanced Edition or Baldur's Gate II: Throne of Bhaal.
Area description[]
This area map can only be reached via interaction with The Spirit Altar.
The area is not directly connected physically with the Final Seal dungeon level.
The "Adventure Level" is some kind of spiritual domain or place that might be only manifested as an intangible thought or dream - it is unclear what this dream scape actually is or where it resides in the planes, if at all.
The area consists of 12 chambers interconnected by passageways and has the look and feel of some sort of underground dungeon.
Accessing this area[]
Gorion's Ward and party will be transferred to this area map by interacting with The Spirit Altar - but only if the Warrior's Skull is in possession by the party.
For information about the adventure challenge in this area see The Spirit Altar and then the Spirit Warrior articles.
Complete the challenge adventure successfully to receive the Spirit Key.
Obtaining the three keys is part of the Unlocking the Final Seal questline.
