Tomer, a Human male, served as a hangar controller at the Bilbringi Shipyards in the era of the New Republic. Around 12 ABY, the renegade Jedi named Dal Konur journeyed to the shipyards and acquired a Firespray-31-class patrol and attack craft, which he then began readying for a venture into Imperial space. During his downtime, Konur used a mind trick on Tomer, manipulating him into assisting with the craft's pre-flight preparations and instructing him to impersonate Konur if questioned. Konur anticipated that Luke Skywalker, who was the head of the Jedi Praxeum located on Yavin 4, might dispatch agents to apprehend him, and he believed Tomer's act of deception would provide a brief diversion against anyone sent by Skywalker during that time.
