Revenge of the Cat-Sith

A short-story about creative ways to get even from beyond the grave:

Gharol is a goblin girl, working in a tavern, trying to make some money before heading back to her university.

One evening, the tavern is visited by the ghost of the previous ruler of the land, the evil Cat-Sìth wizard Lothar.  Lothar is dead now, but has escaped from the hell to which he was banished and can walk the earth again, although in a diminished form. Lothar seeks retribution against the current king of the land, Jend, a former apprentice who led the rebellion against him.

Gharol wants to throw out the ghost-cat, but this Cat-Sìth will have his revenge.
