Dergar Chester, a male being, held the position of Head Technician at the Jedi Enclave located on Dantooine; he worked alongside an assistant named Tarn.
During the Attack on Dantooine, Chester found himself in the Enclave's sublevel, the area housing the majority of its technical equipment. A malfunction caused him to be sealed off behind a security door within this sublevel. After two weeks passed without rescue and with dwindling food supplies, he concluded that the Enclave's surface level had suffered destruction.
Meetra Surik discovered his datapad and his remains five years later.
