His Domain

His Domain is an area in B3313.

Description
The player spawns in a hallway with stairs leading upwards to a double door. Past this door is the main room: an empty room with two decorative paintings, a pit in the middle, and another double door at the opposite end. Going through this door is the back room, another empty area with a small staircase and a passage sealed with a metal block.

If the player moves the metal block, they will discover a small room with a one-way pipe. Though it's not advised to take this pipe...

Origins
The area's layout is mostly original, with the main room and the back room both taking inspiration from two fanmade renders of Peach's Castle best described as "liminal spaces".

The area's music is a variation of "Wrinkly 64" from Donkey Kong Country 3 in a minor key, also known for being used in the ROM hack Super Mario 64: Warped Worlds.
