Chu'lak

Chu'lak was a Vulcan male in Starfleet in the 24th century.

He was born in 2278, and commissioned as an ensign in 2355. His initial posting was to the USS Strata under Captain Jason Stone. The Strata's chief medical officer, Doctor Martin Rackham, diagnosed Chu'lak with a minor psychological instability. (DS9 episode: "Field of Fire")

From 2365 to 2375, Chu'lak served aboard the USS Grissom as science officer. In 2366, he held the rank of lieutenant. (NF short story: "Performance Appraisal")

Chu'lak was one of only six survivors when the Grissom was destroyed by Jem'Hadar forces at Ricktor Prime in 2375. The trauma of the loss of his ship lead to severe psychological problems, and when Chu'lak was later assigned to Deep Space 9, he started a killing spree, murdering three other station residents before he was stopped by Lieutenant Ezri Dax.
