The back of the fortress is a chamber where the fortress guardian resides to guard 2 keys to open the secret chamber to the dungeon.

Both of the structure with doors when unlocked will gain excess a lever to unlock the secret chamber.

With both levers turned, the guardian's chamber is unlocked and allowing a pass to the dungeon where the Golden Dragon is kept.
