Cedric

Cedric is The Author's son. He helps Niko go from the Glen to the Refuge with the flying machine. He has dark skin, white hair, a black hat with a feather on the left side, a pair of goggles with green lenses over his eyes and a smaller pair wrapped around his hat.

Cedric contains KeyG, which is essential in the Solstice run.

In OneShot: World Machine Edition, Cedric's bio reads:

"A prodigious tinkerer and child of the Author. Cedric is the operator of the only known Flying Machine, a miraculous and highly advanced device that can travel the skies. Cedric has been waiting in the Refuge for the day the world can truly be saved. Cedric is hopeful, and eager to play his role in the final gambit."

Background
Cedric, Prototype, Rue, and the Author were all "real people", in that they all lived in the Old World. After the Old World ended, they were all saved as code in The World. During Solstice, it's also shown that he's a pilot and a mechanic, flying Niko to Refuge and being able to fix the flying machine using components from a music box made by the Author.

Personality
Cedric is intelligent and often speaks in a formal manner. It's also shown that he has bravery when he jumped off of a ledge and parachuted down Refuge, and risked his life to bring Prototype back by heading into the unstable factory. He deeply cares about Rue and Prototype.

Trivia

 * The name was first discovered as a leak in the OneShot Discord server's datamining channel.
 * GIR jokingly stated that the character's true name was Gliko/Bliko and that the leaked name Cedric was just a placeholder.
 * It is implied that Cedric and Rue are both robots. This is mainly due to the fact that if Niko talks to Proto before speaking to anyone else, Niko asks Proto what it's like being a robot, and Cedric and Rue respond to Niko's question alongside Proto.
 * This is further reinforced by one of Nightmargin's tweets.
 * According to Nightmargin, Cedric's age is around 16-17 but he appears younger than that.
 * During development, Cedric was originally supposed to be an archaeologist that would translate the strange journal, but that idea was scrapped in favor of the current one.
