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!'

Your thoughts are interrupted by the smol purple lizard who owns the place.
"Oh pay him no mind, Mario just does that. Aaaanyways you're probably here because you want to trade stuff with me, I'm down for it however I'd appreciate it if negotiations take place in Dopcord first."
