Project Archangel is the official designation for a United Empire of Earth (UEE) program to create an artificial planet. Commonly known as Synthworld, the project was announced in SEY 2872 during Corbyn Salehi's tenure as Imperator as a way to move beyond the inherently destructive process of terraforming a planet. The Chronos system was chosen for its Sol-like star and lack of planets in the green band.

Popular at the time, Project Archangel was considered the next step beyond the Fair Chance Act in protecting indigenous life while still allowing the UEE's expansion. The project has since come under fire by the public for the amount of funds poured into it with little apparent progress towards its goal.
