To be clear, as a player I don't have any intent to bring Blagarm along for the ride. Raiyek is mainly just concerned for his well being because he appears to be the only non-adventurer (i.e. maybe not able to defend himself) left in the city. Taking him along would likely not be conducive to an investigation, I think. Plus I agree that old Blagarm probably has a few tricks up his sleeve that Raiyek doesn't suspect.I know there's been some talk about Blagarm joining the others (and I do have a template for a rogue innkeeper), but I think he fits in best as an NPC at the Hanged Man. He can take care of himself despite his jovial exterior.
Oh, you have no idea. You are right on soooooo many levels.Taking him along would likely not be conducive to an investigation, I think.
