Yeah, like, as a QM you want to take a good-faith interpretation of votes, but, again, and I can't stress this enough, we just had that establishing character scene of how Vulkan != the XVIIIth Legion.
It wouldn't be useless! Vulkan and his personal adventuring buddies would be pretty handy for dealing with Konrad himself, and he can act as a witness to our story! If for some unfathomable reason somebody decided to actually kick up a fuss over The Flaying Pits Guy getting shanked, Vulkan's corroborating testimony would be handy! But if you want the Salamnders on board, you have to ask them, not Vulkan.
