The Sanctuary of the Incoherent Stairs of Empty Might is a place in the Deep Void where stairs make audible noises, which vaguely sounds like a language but is just gibberish. There's a man in red and blue performing a strange action that looks like he's being a shrimp on the stairs. On closer inspection, that's Super Duper Gosh Dang Mario 64 performing a Backwards Long Jump (BLJ) on the stairs while rapidly saying 'Yahoo!'

There's a lot of Essence floating around here, but they're intangible to everyone except for Brespawn.
