Either way Vivian will leave it to a vote to the group. Especially once the dwarf comes up to everyone and with sigh telling everyone their paycheck is the lich's ,whatever its actually called, vessel and the will make a lot of them wonder about their client. Or should anyways. Like did the mages guild know about the lich?... and knowingly sent them because they didn't want to risk their own skins?... or is there a darker story to why they were chosen.
