Emewafwawa

He owns Minas Music, a terrifying realm which has influence over the entire area. There is a secret portal in the building which takes you to his opposite dimension in which everything is purply-black and all that can be heard is Erl Koing, the twisted song that emenates around Minas Music.

He prances around and scares all the children by playing Erl Koing, and he also uses instruments as weapons.

This is one of the sources of Emewafwawa's power, after seeing children suffer.
