The Vhorani, also known as the Ancient Ones, were a mythical species spoken of by the early Vulcan people who believed that they resided in Vorta Vor and came to

where they created the Vulcan race. (Last Unicorn RPG module: The Way of Kolinahr: The Vulcans)

The Romulans believe themselves to be the true inheritors of the Vhorani and have embraced the teachings of D'era. (Last Unicorn RPG module: The Way of D'era: The Romulan Star Empire)

The legends of the Vhorani were believed to be inspired by the Arretian colonization of the galaxy, and their seeding of Vulcanoid lifeforms. (Last Unicorn RPG module: All Our Yesterdays: The Time Travel Sourcebook)

This connection is strongly implied throughout the LUG's Vulcan and Romulan materials.
