Avitron: Ephemeris

A young thief's future is locked in a past he can't remember. Without it, the freedom of his world from the tyrannical cyborgs will remain like his youth - a dream. Knights of the Constellations and criminal enterprises. Sorcerers and techromancers. Shapeshifting Morpheons. The cyber-fairy Sprytans. All live on the surface in subjugation under the ever-watchful eyes of the tyrannous cyborg Gensys Tron ruling from their cities in the clouds.
But change is coming. When the fledgling thief, Brayden, steals a relic of the Avitron, the fabric of his reality unravels. The ancient machine holds the power to free the world from cyborg rule, but the secrets of the Avitron and its location lie in a past he can't remember. Now those living on the surface declare war on the Gensys Tron and battle for control of the gravity wells holding the cities of their masters off the ground.
While rebellion rages in the skies and streets, Brayden and his new miscreant friends must gather the components to the Avitron and activate it before the Gensys Tron destroy it for good.
