Narcelleglar was raised in the Silver Reach by copper elves but left during his young adulthood. He carried few of their customs into his future life, becoming a devout worshiper of Nuadun after meeting his mate and taking the form of a human for the first time.
He was a player of the dragons Great Game along with his exarch, Tolfdir Shay. Tolfdir's father Arundel Shay managed to subvert the rules of the Great Game to become a player and defeated many dragons, one being Narcelleglar. This was known by history as the Shining Rebellion and resulted in the death of Tolfdir and enslavement of Narcelleglar to Arundel. His silver dragon mate was slain by dark elf mercenaries near the conclusion of the conflict but he was able to hide away many of his mates eggs. Narcelleglar was governor of Tus after the rebellion and was magically bound to serve Arundel Shay until he was released at the end of the Fourth Age.
During his lifetime, Narcelleglar protected Pahlin Holt, by claiming him as his nephew.
During the restoration of the king, Steinthor Drakeson reformed the Shining Blades as the Reborn Order of the Shining Blade and dedicated the new order to protecting the royal bloodline.
