some drat kender/thief(something or other) has made off with drew's collection of trophy spell-books (every time he defeats a caster he takes their book) He's far too busy to leave his tavern, would you be willing to get them back for him?
the last crusading paladin(s) killed Someone Important(Make up something), he needs someone who doesn't detect as evil to go find and talk the paladin(s) into returning and atoning for their crimes while he keeps the Important Somebody's family from simply ordering a hit on the paladins at fault (or using their political might to have the paladins declared wanted criminals), Drew's a really nice guy, he's nice even to people who tried to kill him.
-Something- happened last night while drew was busy (explain or not), and now one of the doors in drew's tavern is a Gate to somewhere (Sigil? the city of brass? Union? Pick a place) Drew needs to find out what happened, and if the guests on the other side of the door are okay, he tasks the party with this while he prepares to close or move the gate to a better location. It turns for the worst when the party discovers that the guests on the other side have gone through the gate and they need to go through, find and maybe rescue the guests for drew.
Emperor Drew and Innkeep Drew are two different people, and Emperor has heard rumors of Innkeep Drew, Illithid and other minions of Emp Drew begin showing up to investigate Innkeep drew, they find a woman named Kiara staying at the inn
