Rainwing-Nightwing hybrids are this fascinating blend of two extremes, honestly. Rainwings are all about peace, naps, and fruit, while Nightwings brood, scheme, and carry the weight of prophecies. A hybrid would be constantly pulled between a desire for a chill, sunny life and this intense, restless curiosity. They'd probably have the Nightwing intellect and maybe some psychic flashes, but filtered through a Rainwing's more playful, distracted mindset. Like, they could have a vision of doom and then be like 'but wait, first, mango?'
I think the most defining trait would be internal conflict. They'd feel like an outsider in both tribes—too lazy for the Nightwings, too serious for the Rainwings. Their personality might swing based on their environment or mood, more so than other dragons. One day they're a laid-back trickster using color shifts for pranks, the next they're up all night studying scrolls, haunted by a feeling they can't quite name. The camouflage ability mixed with shadow manipulation could make them a master of not being seen, both literally and socially, which feeds into a potentially lonely or secretive nature.
