I know it might not be accurate to the cannon monastery, but I thought it would make it more interesting/creepy, so please don't attack me (or hate it too much, I worked hard on this). Basically I took a lot of references from horror games I like, let me know if you all wanna see more Ninjago Horror Aus (I'm thinking I might make everyone as different monsters too)

It all takes place at night (either early into the night or in the middle)

Songs I recommend for this:

The Lobotomy (Maebi-Topic)

Fallen Down (Undertale)

Granny ost (If you really want it to be creepy)

Abandoned Thrifty Megamart Theme (also if want to be super creepy)
