Nadrinakar was a captain within the Alliance to Restore the Republic, a rank he held throughout the Imperial Era. Following the Rebel Alliance's destruction of the Galactic Empire's second Death Star battle station in 4 ABY during the Battle of Endor, Ca Isiora, a female pilot reeling from the explosion, landed her X-wing starfighter inside a hangar located on the MC80 Star Cruiser Home One. As rebels assisted the traumatized Isiora from her starfighter, she overheard someone beginning to relay a statement made by Nadrinakar, though she missed the full message. Following the rebels' victory, Isiora received care from a medical droid.
The character Nadrinakar appeared in "Galactic Tales: Shockwave," which was the fifth story in the Galactic Tales short story collection. Alexander Freed authored the narrative, which was released on August 15, 2023 in the 220th edition of the Star Wars Insider periodical.
