Star Riders

(In the voice of Neil deGrasse Tyson)
This story takes place in the vast expanse of the cosmos. In a time where humanity has developed enough to leave their home star. Humanity has successfully expanded their influence far beyond what was previously believed. They have covered a percentage of the Milky Way galaxy and discovered new planets. Planets that can foster live and some that already contains life.
Humanity has studied, categorized, and colonized these planets, making them into new homes for future generations to grow on.
These worlds were free from the problems of Earth. They were unpolluted and uncluttered. There was plenty of space that allowed humans to continue to grow without smothering themselves. Also, with their studies, they have discovered that most of these planets possessed a unique energy system with their own laws of use. This energy caused a boost in humanity with abilities that required a new classification to organize the abilities of others and help to grow them to greater heights.
The ones who discovered these planets were given major benefits and saw their life improve to grand heights they were the first Star Riders. With such rewards many wanted to become Star Riders. To ride the endless sparkling sea of stars and find new planets, new challenges and further rewards.
Our main character for this story is the first child of a Star Rider. The Star Rider was Alexander Xenos, the discoverer of Planet Xenos.
A boy born with a sickly body with a disease that eats away at his own flesh and forced to replace parts of his body with robotic enhancements, let's see how his story unfolds.

side note: The disease will only be relevant to the mc's back story and replace his mortal body with mechanical parts will have consequences for the mc in the beginning that he'll have to overcome.
