Bright was one of the RainWings briefly mentioned in The Hidden Kingdom as being imprisoned by the NightWings. He was one of the RainWings who died in captivity on the NightWing Island, along with Tapir and Orangutan. It is unknown how Bright actually died, but it was likely related to the food they were fed and/or the harsh conditions of their imprisonment, due to the scarcity of food, sunlight, and other necessities on the island.
Shortly after Glory challenged Queen Magnificent for the RainWing throne, Kinkajou defended Glory's decision from nearby dragons who wondered whether they really needed a new, "proper", Queen. She sarcastically suggested they should ask Gibbon, Orchid, Splendor, Tualang, or Loris their opinion. Kinkajou then stated that they (along with several other RainWings) were all imprisoned in the Night Kingdom, with the exception of Tapir, Bright, and Orangutan, who had "died awful deaths, alone and far away from everything and everyone they loved", and that Glory was the only one willing to do anything about it.
