Lernik De'Yago was a male arms dealer of the Rodian species.
Prior to the year 3 ABY, De'Yago, functioning as a dealer of weaponry, would sometimes engage in transactions with the Alliance to Restore the Republic at their base situated on Asher III.
In the time leading up to the battle of Hoth, the Galactic Empire discovered the location of the Asher base and launched an assault while De'Yago was present. During this conflict, the Empire seized De'Yago's weapons shipment without providing compensation. De'Yago observed the Nova Whisper, an illegally-modified Short Hauler utilized by the Rebels as a medical vessel, leading the Rodian businessman to commandeer the spacecraft to facilitate his escape.
Due to the Empire's near capture, De'Yago embedded numerous credit-account access codes within a subroutine of the nav computer, while erasing it from his personal datapad; this action ensured that, in the event of his capture by the Empire, his hidden wealth would remain concealed. To retrieve this data, he only needed to chart a course for the Noquivzor system, at which point the ship would recognize the secret code.
However, De'Yago had incurred significant financial setbacks. To recoup his losses, he proceeded to sell the Nova Whisper to a starship vendor located on the Ithorian Herdship known as the Bazaar.
