The ghost inkeeper is the owner of The Green Ghost tavern in Port Phasmatys. Like the other residents of the port, he made a deal with Necrovarus to protect themselves from the vampyres by using the power of the ectofuntus. However, they unwittingly allowed the ectofuntus to turn them into ghosts. He continues to run his business, leasing out a room to Robin and allowing a brewery to operate in the cellar of the tavern, though the taps on the bar have long since run dry.
During an attempt to free the port from Necrovarus's control, he asked an adventurer to give a bedsheet to Robin.
