Lenik
Lenik of Vulcan is a 131-year-old Vulcan and an extremist member of the Reya-Laialara. The commander of an old alien frigate that has been re-purposed for pirating and navigating through the Shoals, he's made a name for himself for his brutal tactics, uncompromising devotion to a fundamentalist version of the Reya-Laialara's ideals, and his ability to thus far elude authorities. Lenik is suspected of having committed several murders simply for the emotional experience.
History
Lenik was a priest on Vulcan up until the early 2350s, and showed no signs of radicalization or emotion. What happened during this time period is unclear. However, when Lenik re-emerged outside of Federation space twenty years later, he was a very different man. Shunning Vulcan philosophy in exchange for emotions running rampant, he didn't take long to take to apparent piracy.
