- second level of the labyrinth beneath the fortress -

a music room. flutes, a piano, drums, violins, harps, celli, trumpets, an endless amount of sheet music. and weirdly a pair of red boxing gloves.

"But if Pekka Rollins kills us all, I'm going to get Wylan's ghost to teach my ghost how to play the flute just so that I can annoy the hell out of your ghost."

"I'll just hire Matthias' ghost to kick your ghost's ass"

"My ghost won't associate with your ghost."

- Jesper, Kaz and Matthias in "Six of Crows"

it says on a sheet of paper somewhere between all the piles of sheet music.
