Youngest daughter of Denarum Idarra, successful architect from Tash-Murkon Prime. Studied architecture at the Royal Institute and graduated with honors. Instead of pursuing a career in her father's firm, joined the Imperial naval academy, earning ace status in the Imperial fleet with 13 confirmed combat kills before becoming a capsuleer. Recruited by the then-Reform Pilots' Union (later the 501st Revolutionary Brigade) in YC 116. Earned outlaw status in the Amarr Empire upon the failure of the 501st's coup attempt and its dissolution in YC 117. Subsequently disowned by her lineage (the Tash-Murkon line of Clan Idarra). Joined Nortalia Stormwalker in the Alliance of Privateers in Caldari space, where they became lovers.

Currently travels into and out of Amarr/Khanid space under an alias due to the existence of a perpetual open warrant for her arrest (initially a kill-on-sight order, but due to a statute of limitations loophole exploited by her clan's legal represenation this was reduced to a general arrest warrant in YC 119). That being said, Talonix generally avoids travel into Amarr/Khanid space if at all possible.

The Idarra are a family of Ni-Kunni architects and engineers who were in the employ of the waterlords of the Ni-Kunni homeworld of Mishi IV prior to the planet's conquest by and integration into the Amarr Empire. Like most Ni-Kunni, the Idarra integrated into Amarrian society well and due to the family's talents the Idarra were in Amarrian slavery for less than a decade (far shorter than even their fellow Ni-Kunni) before being employed again as builders and engineers.
