On main gallery because I'm kinda proud how it turned.

He's Orville's big brother, Wilbur, died in a crash while trying the wing his little brother made for him.

Human age: 39 years old
Description: Wilbur was a proud member of the Sky Gendarmerie clan. He was the best aviator the clan ever had, and the medals on his jacked prove it. During a war, he had lost his right wing, and his ability to fly like an eagle.

He was Orville's hero, and he knew that. He always tried to gave his brother the good example, worried about his health problems (Orville had a lot of them), and always kind and gentle.
Orville thought to do something to make the brother fly again. He made a fake wing for him (he wasn't working on his own in this time), with a rope to action it.

The day to try the wing came. They tried first with low heights, and then the great moment arrived: the true flight. Wilbur jumped from a plantform of their world (a steampunk-like city that floats in the air) and the moment to open the fake wing came, too. But something didn't worked. The rope were blocked in the mechanism that should have opened the wing, and it remained closed. A scream in the sky, and Wilbur disappeared in the dark clouds of the Sky Gendarmerie. The body was never found.
From that moment, Orville always felt guilty.
