Menzala Trivere was a male native of the planet Vrinda in the 24th century. A brilliant scientist, he was purported to have worked to create a global null field generator which would render that world's astral projection technology useless. Instead, he was secretly working to make that projection available to every person on the planet.
In 2376, Trivere faked his own death by creating a projection of his own corpse, and framed Federation cultural specialist Martin Mansur for his murder. Trivere was discovered by his former friend, Alhouan and Starfleet scientist Carol Abramowitz. (SCE eBook: Age of Unreason)
