Skyrunner was born to two DriftWing nobles. Her egg was stolen by Cassandra, a nomadic hybrid who had a bone to pick with Sky's parents. When visiting the RainWings as ambassadors, the two DriftWing nobles came up with the idea to tear down Cassandra's house to make a brand-new trading post. Because of this, Cassandra was enraged and took her anger out on the couple's egg.
Deep in a hidden hollow of the rainforest, Cassandra cursed the dragonet that would hatch from the egg to have the power of knowing. The dragonet would be able to think at top speed, but it would also be cursed with insecurity, paranoia, and nervousness. The curse would allow the dragonet to know what was going to happen in Pyrrhia (this was not planned as precognition, but as high intelligence), but it would be helpless to stop it. Cassandra left the egg at the outskirts of the DriftWing kingdom, and then was on her way.
Skyrunner's parents wore themselves out looking for her egg, mostly because she would be the one to carry their noble blood to the next generation. Skyrunner, in the meanwhile, learned to survive in the alleys of the Goldtouched City. The city may seem like paradise, but the low-class citizens see it as something else. Beyond the "great fortune" and the "fresh starts" that are described in history books, there are back roads and abandoned buildings where thieves and lowlifes deal with one another. Skyrunner grew up there, learning how to steal and manipulate others. She learned from many criminals, gaining knowledge from each of them as she went on. She was taken in by the crooks of the city because they could already tell she was tough and would fit right in as one of their own. At first, she only assisted in petty thefts, but with all of their help and training she was able to become the most wanted criminal of the DriftWing kingdom.
After one of the dragons who taught Skyrunner about stealing was killed by the royal guard, she began to harbor a hatred for DriftWing royals. Their guards had killed a dragon mercilessly without any sort of trial, and she was horrified by it. The death of that dragon made her realize that everything her "teachers" had been telling her about the high-class DriftWings was true - they didn't care at all about their subjects. Though Sky's loathing of the royals was misdirected, she thought that she was right - and still does. After this incident, she began plotting to steal as much as she could from the royals.
As Skyrunner grew older, she began to trust very few dragons. She had seen plenty of thieves backstab one another - literally - and she wasn't planning to get herself killed. There are a select few that know about her heists, but she rarely ever sees them. However, Wolfstep is one of her closest friends. He doesn't know her whole secret, but he knows that something happens in her free evenings and helps her out when he can.
Sky moves around often. One day her temporary home will be a run-down apartment penthouse, and another day it'll be the unused storage room of the most popular restaurant in the city. Sometimes she hides in plain sight, and sometimes she doesn't, but she'll always be able to evade the DriftWing guard.
Sky plans her heists during the day, and carries them out in the dead of night. She doesn't know who she gets her intelligence from (she thinks of her intelligence as a curse, and she believes magic may have something to do with it).
The Curse of Knowing
This curse of Knowing was created by Cassandra and altered specifically for Skyrunner's egg. Skyrunner's egg never making it back to her parents was a part of the punishment, but the curse was even worse.
The curse does not gift Sky with precognition, but instead gives her high intelligence that comes with a deep insecurity. She's always paranoid about the dragons around her, and her already introverted personality is taken to the next level. She gets anxious often, and of course no medicine for that has been invented yet. However, she is able to hide her nervousness for most of the time, and her heists help her channel her intelligence and quick observation into something she enjoys. Reading scrolls does the same thing for her.
The curse multiplies the accuracy of her peripheral vision. Even a flicker of movement seen out of the corner of her eye will be registered. This comes in handy, as thieves need to make quick escapes often. The curse may or may not be the reason Skyrunner is terrible at combat. Her figure and muscles suggest she could be ferocious in battle, but perhaps as the curse strengthened her mind, it weakened her physically.
