Doctor Xin Ra-Havreii was an Efrosian engineer and designer who served in Starfleet in the 24th century.

For over four decades, Commander Ra-Havreii worked as a theoretical engineer at the Utopia Planitia Fleet Yards. As well as working at the "Skunkworks", Ra-Havreii spent some time as an instructor at Starfleet Academy in the early 2360s. Sonya Gomez was one of his pupils. (TTN novel: Taking Wing; SCE eBook: Many Splendors)

In 2369, upon the discovery of the Bajoran wormhole, while at Utopia Planitia, he began working on design for the Luna-class. The project was suspended during the Dominion War, but renewed afterwards. He was aboard for the launch of the USS Luna in 2372, which underwent a terrible accident, killing many of the crew.

In 2379, Ra-Havreii boarded the USS Titan and requested that he remained aboard for the duration of her shakedown cruise, a request which was granted by Captain William T. Riker. He was later assigned as chief engineer following an engineering disaster which killed Nidani Ledrah. (TTN novel: Taking Wing)

While aboard the Luna, Ra-Havreii was involved with an Efrosian woman named Dree. As chief engineer of the Titan, he has had at least one sexual encounter with conn officer Aili Lavena. (TTN novels: The Red King, Orion's Hounds)

While aboard the Titan, Xin became enamored with chief science officer Melora Pazlar. Feeling as though her handicaps severely limited her, he designed and built a holographic stellar cartography tank for her, allowing for direct access to information and a projected holographic avatar to interact with other crewmembers of the ship. However, when Xin attempted to express his affections via a kiss, she turned away, refusing the contact. (ST - Destiny novel: Gods of Night)

After the Titan made orbit of New Erigol and informed by the Caeliar that the ship would not be allowed to depart, Riker assigned Pazlar and Ra-Havreii to search for non-tactical weaknesses to exploit. Ra-Havreii was unable to get clear readings of the sphere, but was impressed by the engineering required to construct it. The Titan prepared a strike team for the planet; during the attempt, Xin attempted to activate the folded-space transporter, but the attempt was aborted when a scrambling field prevented the transport from working. Ra-Havreii was later visited by Counselor Huilan Sen'kara after he visited Pazlar. Huilan asked Xin to shut down or dismantle the holotank, believing that Pazlar was beginning to use it as a crutch. Huilan then questioned why the tank was constructed, suspecting that Xin was projecting his own emotional needs onto his fellow officer. After continuing to work, Pazlar and Ra-Havreii were able to discover the soliton pulses keeping open micro-subspace tunnels and then tapped into them to witness the invasion of the Borg Collective at the Azure Nebula. (ST - Destiny novel: Mere Mortals)
