Glorybringer

Glorybringer is the canon ship between Glory of the RainWings and Deathbringer of the NightWings. The two of them meet at the beginning of Book 3, The Hidden Kingdom, when Glory is disguised as an IceWing. She hints to herself that she thought Deathbringer was cute but only before she realized that he was there to kill them.

During the end of Book 3, Deathbringer saves Glory's life, confirming his love for her too. During Book 4, The Dark Secret, Glory saves Deathbringer's life and Starflight notices that when Glory and Deathbringer exchange looks, they exchange a 'look of thanks and something more'. During Book 5, the Brightest Night, and beyond, Deathbringer becomes Glory's unofficial bodyguard, and Glory sometimes hints that Deathbringer is 'not being romantic at all'.

Sunny also wonders if the two will ever have dragonets, and it is confirmed in Moon Rising in a possible timeline, they have a hybrid dragonet named Firefly. Tui, the author of the series, has confirmed several times that Glorybringer is canon, and the two are dating.
