Tole Warren served as an officer in the Rebel Alliance, possessing a dual heritage of half-Human and half-Morellian.
Tole, the offspring of the Morellian Barosa Warren and an unidentified mother, carried his father's surname, despite their eventual estrangement. Barosa viewed Tole as an adversary due to Tole's affiliation with the Rebel Alliance.
In the year 3 BBY, Tole Warren assumed the role of communications officer for the Rebel Alliance within the Suolriep sector. Additionally, he actively participated in field operations and dedicated the remaining portion of his time at the Delta Base command center, functioning as a high-ranking officer under the command of Vanden Willard. He held membership in the Rebel Alliance Task Force and worked as a cryptographer, tasked with deciphering crucial Imperial communications.
In 0 ABY, Warren received an assignment to the Silent Water. During this period, the Alliance detected the presence of the bounty hunter Kal-tan-shi within the Veron Minor system. The Alliance sought to track Kal-tan-shi and enlisted Warren's assistance due to his fluency in Tiss'shar, a necessity given Kal-tan-shi's aversion to droids (a revelation that initially unsettled Warren's protocol unit, though she ultimately adapted). Although Warren's efforts to locate Kal-tan-shi proved unsuccessful, he observed an anomaly on Kal-tan-shi's ship, the _Accuser_: a bug affixed to its starboard thrust converter. Warren documented this observation for inclusion in his report concerning Kal-tan-shi for the Task Force.
Warren's deployment to the safeworld of Stronghold occurred in 1 ABY. He numbered among the few who survived the Battle of Stronghold.
