Yades was a pilot of a starfighter; he served with Devil Squadron of Grace Command, a group of volunteer fighters headed by Baron Lemayne. This squadron fought for the Galactic Republic during the era of the New Sith Wars. Although Grace Command was ostensibly a humanitarian aid organization distributing supplies and fighting the Sith warlords, its true purpose involved the distribution of the drug Deluge in worlds controlled by the Sith. During the Battle of Capital Cay in 1032 BBY, Yades and his Devil comrades engaged one of the Stormdriver vessels belonging to the Hutt crimelord Zodoh. After the liberation of Capital Cay, Yades took turns with the crew of the transport Mother Grace, which allowed the Jedi Knight Kerra Holt access to his Fire Lotus-class starfighter. This choice by Yades ultimately saved his life, as Zodoh eliminated his entire squadron, with the exception of their Captain Jenn Devaad.
