Horvik was a member of Vengeance. Part of the second team sent to disrupt activity in Drev'starn, he was assigned to cover up the work of Drend Navett and Klif in taking out the city's deflector shield generator. Horvik, along with Pensin, posed as janitors at a Ho'Din cafe near the generator site. From there he helped dig a tunnel into the room housing the power generators for the shields.
When Agent Navett was ready to finish the operation, Horvik, Klif, and Pensin, disguised as New Republic technicians, managed to get aboard the Ishori war cruiser Predominance. Killing their escort, they managed to fire several turbolaser rounds at Drev'starn before being discovered and neutralized.
