Ralen Margok, a Zabrak individual, belonged to the Nova Blades pirates group, existing over one century prior to the year 3637 BBY. When the pirate starship named Aggressor experienced a crash landing on the planet of Rishi, Margok was present. He and the other pirates were vital in transforming the downed ship into the headquarters for the Blades. Consequently, Margok's lineage, which includes Dael Margok, rose to prominence within the Blades in the subsequent decades.
The Codex entry for Ralen Margok's descendant, Dael Margok, in the 2014 Digital Expansion Star Wars: The Old Republic: Shadow of Revan for the 2011 BioWare video game titled Star Wars: The Old Republic, contained a mention of Ralen Margok.
