I'm leaning cemetery, especially because it looks like we're right there beside it.
Me too. Knowing who the dragonborn is at the very least might help focus future investigation, even if we don't get the chance to use our speak with dead token. And we may get to talk to this Grom Skullsmash. I reckon Brother Alabaster knows more than he's letting on, though.
I've been trying to work out if we actually know who asked us to investigate the murder we came across first?
I think when all this started I assumed we were working in some sort of official capacity, but that's clearly not the case. Even the intro vid doesn't make it clear who is employing us, though I now wonder if the creepy voice is Fel. Could he or his master have hired us and the whole thing be a setup? It's not clear why they'd want us looking into the death if they caused it, but they do seem to want us trying given the note we received challenging us to do so in ten days. Could the dragonborn or the beardless bard be private investigators too, hired to look into crimes and led into a deadly game which they failed to complete in time? It's not clear how that would tie into the butcher's death though.
