I think it might be interesting to have a bouncer/ janitor NPC rather than a tavern owner, for a few reasons...
1) She could be a female character, like a female stonebreaker say, who could drop you with a sneeze. Maizebel Lumenstone... red hair please... no beard!

2) Bouncers always know everything about everyone but require creative bribes before they divulge information- could make for fun quest chains

3) A short female bouncer would be funny, maybe she could be funny too?
4) She could have keys to places like those buildings outside the Stonehead, or the secret doors inside, that could eventually lead to mines under the stalactite or some secret wonderful treasure trove

5) Somebody has to keep their ears on the clientele, and janitors are notoriously invisible to certain types of patrons

6) She could train sword or melee or something, and sell crafts and items on the side (imagine her rolling up her sleeve to reveal a dozen of Gugrontid's equivalent of Rolex knockoffs!)

7) Elady is the owner/ boss and she makes the best pies in the land, so no cheap imitation tavern owners please!
Just my thoughts...
