An Er'Kit male named Andrik Keller was a Nihil marauder. This individual held the Strike rank within Lourna Dee's Tempest, known as the Tempest Runner. He served on the starship called Lourna Dee. During the Battle of Galov, Dee promoted him to Storm. This promotion occurred after the Nihil, facing superior firepower and numbers from the Galactic Republic and the Jedi Order, were compelled to abandon the starship. Although Keller successfully fled, many Nihil were captured; Dee herself was among those apprehended and taken to Starlight Beacon by the Jedi, who were ignorant of her true identity, thinking she had died during the conflict. Keller received information from another Nihil who had also escaped, informing him that the captured survivors were being held. As a result, Keller traveled to Sran located in the Ash Worlds, with the intention of assembling a crew to launch a rescue mission. While on Sran, Keller crossed paths with Pan Eyta, a former Tempest Runner who was secretly seeking vengeance against Dee for his perceived betrayal. Under the influence of several drinks, Keller began to talk about the events of the battle, and revealed Dee's current status. Following this revelation, Eyta murdered Keller before setting off in search of Dee.
