Ectair

Ectair was a neutral planet located within the boundaries of Federation space.

In 2273, the planet was visited by a squadron of Romulan vessels. When the USS Ardent arrives to investigate, a senior planetary official mediates the situation.

A year later, representatives from the United Federation of Planets and the Romulan Star Empire sign the Treaty of Ectair. (FASA RPG: Star Trek IV Sourcebook Update).
