The deceased Captain Telaka
Starfleet Captain of the starship USS Lantree. He, and the rest of his crew, were killed following their visit, in 2365, to the Darwin Genetic Research Station on Gagarin IV. Telaka, who was only 30 years old at the time, died of premature aging caused by the antibodies of the genetically engineered children that he was exposed to while at the Darwin Station.
