Born in 2231, Razka spent over one hundred years in Starfleet as a noncommissioned officer, never once having committed insubordination. In that time, he had fought the Klingons in the 23rd century, the Tzenkethi and the Cardassians in the middle of the 24th century and faced both the Borg and Jem'Hadar in combat.
In 2266, then Senior Chief Petty Officer Razka served aboard the USS Sagittarius, an Archer-class scout vessel, as a field scout. At the time, the Sagittarius was assigned to Starbase 47 (aka "Vanguard"), in the Taurus Reach. (VAN novel: Reap the Whirlwind)
In 2379 he was part of the Alpha team under the command of Commander William T. Riker which was sent to Tezwa's Mokana Basin to destroy the nadion-pulse cannon firebase located there. He had irises which gave him thermal vision which he was able to move over his eyes by blinking and he was able to travel faster through dense forest barefoot than with boots. He was killed by Tezwan soldiers while attempting to defend the unconscious Commander Riker. (TNG novel: A Time to Kill)
