A former slave of the Centauri himself, he was the owner of the contractual slave Adira Tyree. In 2258, he forced her to seduce Centauri Ambassador Londo Mollari so she could steal his Purple files, vital information about the Centauri Noble Houses he hoped to sell to the Narn Regime at a high price. After she kept delaying, he insisted she use a mind probe to get the data.
Adira successfully stole the files, but had actually fallen in love with Londo. She arranged to meet up with Trakis in the Zocalo and hand over the files, but overcome with grief she fled from him instead. Trakis decided to approach Mollari for him, telling him that he had no part in the theft and that Adira was secretly a Narn agent. He plants a listening device on Londo, which enables him to learn where Adira is as soon as Londo does. Trakis hires some thugs from N'Grath to delay Cmdr. Jeffrey Sinclair and Londo long enough for him to seize Adira.
Trakis then meets with G'Kar, as G'Kar has been duped into believing he will actually obtain the files. Wary when he arrives and telepath Talia Winters is present, Trakis is tricked into revealing Adira's location. Attempting to flee, he is knocked out by Londo, who recovers his files and rescues Adira. Afterwards, Sinclair "convinces" Trakis to free Adira.
