As an aside, as a rogue I was able to unlock the subterranean entrance at the beach (perfect place for an undisturbed crypt, those idyllic, temperate shores, noone would ever notice them there) and the encounter is even more inexplicable running into them from that direction. They are hostile with no introduction or explanation of who they are, what they are doing, and why they are attacking you. You just figure out how to open a door and find yourself immediately in combat. After slaughtering the lot of them you emerge with two dialogue options which result only in combat, or what is left of the band dispersing.
