Hermeticus II

Hermeticus II was a planetoid in the far reaches of the Neutral Zone. It was placed under quarantine by the United Federation of Planets in the mid-24th century after the USS Independence was lost investigating it.

In 2368 the USS Enterprise (NCC-1701-D) and the Romulan D'Kazanak-class Warbird rediscovered the planet. Further investigation revealed that Hermeticus II was in truth a starship, which was spherical in shape. It was inhabited by the Ambimorph. (TNG novel: "The Romulan Prize")
