Well Bottled at Slab's — John Gregory Betancourt

Slab's tavern is the roughest bar in Zelloque, frequented by pirates, slavers, thieves, and other less savory patrons. It's also haunted ... and you never know who--or what--will show up. When a young wizard-in-training comes to Slab's Tavern purportedly to study the ghosts, no one realizes he's merely a tool of his master ... who has an old grudge to settle! This is the second of the Slab's Tavern stories.
