Gestalt Prime

Pre-sync Earth is no more. All that remains now is a barren planet devoid of its atmosphere. The oceans that once covered the majority of the surface have boiled away into space. Shielded from solar radiation, the remaining few humans survive under the protection of the Citadel barrier.

Alexia did not ask to be a test subject for the Controller Program. Brought up to the surface from an early age alongside dozens of other orphans, she underwent extensive cerebral cortex modifications that would allow oversight of the barrier via direct encephalon connections.

Only a few test subjects survived the Program and those who did became bound to the host-Controller symbiosis.

Driven to apparent insanity by the Program, a childhood friend of Alexia's has used the technology that once saved humanity from extinction against them. In the aftermath of genocide, the Program is in lockdown and she faces suspicions of aiding the rogue.

Determined to clear her name and understand her former mentor's madness, Alexia follows the trail left behind by the rogue unaware that along the way she will learn the secrets of the Program, the true circumstances surrounding the catastrophe that 246 years ago ended the world and rediscover the past she thought she had moved on from.
