Doric was a landlord on Kelemane's planet who owned a residential building in the Central Protectorate.
The Doctor stayed in this building when he was sent to the planet to gather information in 2376. Because of a space-time displacement, The Doctor was on the planet for a little more than three years, while the USS Voyager was only in orbit for approximately twenty minutes. During that time, the building was destroyed when a short war erupted between the Central Protecorate and a neigboring state.
Doric loved to speculate about the Sky Ship. (VOY: "Blink of an Eye")
