[Sorry Taako, but Khadgar would have to agree with with Varian.]

I've not seen anything like this before, but it does look too clean for orcs. There's not enough destruction for one thing. [He's seen enough by now of the carnage the orcs left behind when they attacked places or people to know that this was definitely not done by them. They likely would have used the man's instrument to bludgeon the player of it to death with brute force. Not garrote him with a string from it.]

I can't help but think whatever did this was actually careful not to disturb anything that didn't fit with the image they wanted us to see.
