The Hall of the 42 judges

The hall of the 42 judges is a structure found near the end of Duat's journey. It is the location of Ammit, the final boss of Egyptian mythology.

Layout
The hall is a massive structure, eclipsed only by Bilskirnir and the town that surrounds Valhalla, both in Asgard. The hall is a rectangular two story building, with a two layered terrace in front of it, with a massive pylon in front of that. The structure is surrounded by a layer of columns, and has two exterior staircases to access the upper level. The Interior is built around a massive endless pit, enveloped by a walkway on both levels, which features the seats of the 42 judges. The endless pit in the centre also has a platform, which is accessed by a bridge, and leads to the exit by an incomplete bridge. This platform contains both the scale of judgement and the summoner to Ammit. Note that the scale is necessary to summon the boss.

The scale of judgement and summoning Ammit
To make the summoner activateable, the player must use the scale to perform the weighing of the heart. A chest with both a heart and the feather of Ma'at is found in front of the scale, and each plate of the scale is labeled with each item, prompting the player the player to dump each item in their respective plate. Only then can the player activate the boss summoner.

Activating the summoner will lower the plate containing the heart, and inform the player than he has failed the weighing and must face Ammit.
