Naoise
Dragon partnered with Deirdre
Naoise was the Dragon partnered with the Dragonlord Deirdre. Skye's royal account portrays him as an invader slain by an ancestor, while survivor accounts say Deirdre came to repair relations and was killed, her body then used to lure him into a trap. Celestia believes their remains suggest that he carried her to their final resting place.
