What everyone thinks happened: Clearsight arrived on Pantala and mated with Sunstreak. Their children were the first ever HiveWings. The children mated with their siblings and, due to inbreeding, they gained the powers HiveWings have today.
What really happened: All 10 of the flamesilk families are all descended from NightWings, which is why Queen Wasp doesn't want any SilkWings knowing what flamesilks are. They have their black scales painted over by the HiveWings when they get their ID marks are burned on. HiveWings have their black scales painted onto them when they're born, so only the Royal family knows the truth. Wasp started this rumor when she took over the SilkWings, but the LeafWings knew they were lying, so they went to war. That's why everyone thinks LeafWings are evil.
