So this is Skarn, the lieutenant from Manor of Ravens

This is all that is known about him from the book that I can find:

So, my question is, what the heck is the explanation for the fiddle on his back?!

So it’s the fiddle that bothers you, not the doorknob-on-a-bird-cage head or the pyramid-of-books leg, huh?

Wizard casts spell on manor to protect it from intruders. Wizard dies, forgets to turn off the alarm. Trespassers ...trespass... at the manor, and awaken the guardian (skarn). Said guardian is composed of pieces of the manor itself, as he is a magical construct. Hence, he's made of books from the library, a chandalier, the door knocker, a fiddle from the music room, etc.

I think I have the answer, clearly Skarn won- or was he the challenger?.... https://www.youtube.com/watch?v=7EY9kB2n8wk

For some reason when I saw it my brain decided it was something he was carrying around with him, not a piece of his construction. I just couldn't wrap my brain around the idea of this thing pulling out his fiddle and starting a jam session with a bunch of goblins.
