Hj'olla was a female Tiburonian Starfleet officer in the 24th century. She graduated in 2376, one year ahead of schedule, and was commissioned as an Ensign. A computer specialist, she was temporarily assigned to the Starfleet Corps of Engineers. In late 2376, she joined the USS da Vinci at Starbase 212 for a mission to Coroticus III, to recover and reestablish the cultural observation post abandoned there over two years prior during the Dominion War. During this mission, she formed an attraction to Crewman Fabian Stevens, though it never progressed beyond innocent flirting. (SCE eBook: Fables of the Prime Directive)
