Migress was a male Brolf working under Patriot (Filvian) on the planet Barlok to assassinate Passel Argente in 27 BBY, when negotiations were held on the planet between the Corporate Alliance and the guildmaster of Barlok's mining operations. Migress received burst thrusters from his fellow conspirators (Duefgrin and Jhompfi) to contribute to the building of a homemade missile to be used for the assassination attempt against the Corporate Alliance leader.
