Thelka IV was the inhabited fourth planet in its system. This was home to a special sort of dessert.

Prior to 2369, Captain Picard, while on a visit to this planet, first tasted this dessert. In 2369, Picard wanted to share this dessert with Nella Daren, but was prevented from doing so by a fire storm crisis on Bersallis III. (TNG: "Lessons")

This planet was only mentioned in dialogue.
