A fire simmers in Sol...

For decades the Psion AIs have lain dormant on Ceres, seemingly content to hold their single InnerSol world without moving deeper into the system - but that's about to change.

After decades of failed diplomacy, Weapon Born AI Lyssa knows that Psion is preparing to make a move and she keeps vigilant watch over their actions. Meanwhile, Marsian special forces, Sol data hackers and smugglers from Cruithne all find reason to turn their eyes toward Vesta.

Vesta - the largest asteroid in Sol, and home to countless ruins, miners, junkers - and secrets. The oblong rock is nearing Ceres, coming under increasing scrutiny as the militaries of InnerSol converge, driven by a potential end to the decades-old standoff between humans and AIs.

And a beginning to war.
