So tell me what are some of your favorite headcanons for flight rising? I know I just kind of collect some as I go along.
Hmm, I have a bunch, lemme try to think of some.
Nature dragons believe that their bright arrays of colors are gifts from the Gladekeeper, who bestows them upon them at birth. Every color is believed to have meaning and correspond to something in nature. White colored dragons are compared to bone, or snow, and they're considered omens of death, with one foot in the world of spirits, and often cursed or unlucky. White nature coatls are shit out of luck.
Every flight has a bunch of "typical" manifestations of their own magic in dragons who use it, usually variations on direct physical control of that element as seen in the arena. Every element also has a number of atypical manifestations of magic, and those born with it are able to do unusual things that most dragons of that flight can't. A lot of those are a result of mixed elemental ancestry. At least one of every atypical type of magic is considered monstrous and anathema by that flight. For instance, most ice dragons can call up a deep freeze or an icy bolt. An atypical type of ice magic is being able to scry in the reflections of ice, usually seen in ice dragons with water ancestors. The monstrous atypical ice magic is the ability for a dragon to change themselves into a ghostly creature of icy wind, deadly, dangerous, and near impossible to injure, capable of shredding flesh from bone within minutes. They're called Wendigos, and ice dragons tell stories about them on dark nights when the winter winds shriek outside their lair.
Sornieth has no official currency. Treasure is the colloquial term for gold coins, but any clan with a smith can mint their own, and it's considered kind of a point of pride to have coins with your clan's name and symbols stamped on them. Most merchants carry a set of scales, because the coin size is nothing resembling standardized, and you have a real problem when "100 treasure" is 10 ounces of gold in one clan, and 50 ounces of gold in another. Particularly artful or beautiful coins have extra value though, and are sometimes made into jewelry.
It's unusual for every dragon in the clan to have a familiar. Familiars are generally expected to earn their keep, usually by helping in hunting. It's a status sign for a clan to be able to support a lot of extra mouths, particularly when they're purely for companionship or decoration.
A lot of dragons like to form permanent mated pairs, but polyamory among dragons is pretty common as well. There's no cultural taboo about this, it's just sort of accepted as the way things are.
Dragon religion is kind of..... really simple honestly, since the gods are indisputably real and around and don't demand much except exaltees. There are still some really weird cults, saints, and shrines though. Sometimes it's just a silver-tongued, charismatic shadow dragon looking for a fast way to drum up followers by proclaiming themselves to be a godlet, sometimes it's a water dragon having holy visions, sometimes it's a light dragon who's found an "ancient scripture." Usually this stuff is pretty harmless, and doesn't leave behind anything worse than an odd shrine to The Shadow At The Crossroad or a group of devotees to Our Lady of Jade, but the emperor worship cult managed to raise half a dozen and run into their maws in an ecstatic frenzy before the deities stepped in for some very pointed theological debunking.
Noggles are important. Noggles are so important. The final Beastclan boss is going to be a Noggle.
