Captain Jerok

Captain Jerok is a Federation Starfleet officer and the commanding officer of the Federation starship Yorktown. Originally a Romulan science warbird commander, after the Shinzon Incident he was granted Federation asylum as he increasingly became disillusioned with the Romulan Star Empire's handling of their internal political problems and existential crisis. Over the years he gained the trust of the Federation and Starfleet on various projects earning him a commission as a Starfleet officer and was eventually given a command of his own again.
