Gravity Dreams

Gravity Dreams centers around main character, Tyndel, who was raised in Dorcha, whose culture uses the philosophy of Dzin as a means of social control.

He is taken to a medical facility after experiencing weird lights across his vision, and told that he was infected with an ancient strain of nanites that would have killed him.

He rejects this training and is instead transported to Omega Eridiani, where he spends three years in a menial job, low in the Rykasha social ladder.

Tyndel gets involved with a colleague, and when she dies in an accident, he begins to question his choices, eventually requesting to return to web-jockey training.

He undergoes extreme training to improve his physical condition, and repairs his relationship with Cerrelle, while also beginning to again experience distorted vision.

It is an entity called Engee ('Nanite God'), telling him that it requires his consciousness to act as an observation platform for a reverse-energy universe.
