"So, shall we begin?" Irenaeus asks us all.
We all just nod in agreement as we begin navigating this final dungeon that screams "the very definitely final dungeon" more than the supposed final dungeon, with all the symbolic imagery plastered all over the place.
Area 1, Entrance.
This is where the Forgotten Realm begins, Captain Obvious.
This area is composed of four really large white tiles, all stuck together by some supernatural glue or something, that are all floating above the clouds over Daig'digaia.
The tiles are arranged in a diamond pattern, and the upper and lower tiles contain portals that lead to the next area and back to Daig'digaia, respectively.
As for the left and right tiles, they are accompanied by a pillar of light each that is totally harmless when touched.
And to allay the fears of the acrophobiacs among us, the entire dungeon has a special enchantment that automatically detects a person's fear of heights and deactivates it, right in their brain.
