The rebellion founded by Ares against Gold rule, now led by Sevro from the hidden base of Tinos and hunted across Mars.
The Sons of Ares, the rebellion founded by Fitchner/Ares to break the chains of the Color hierarchy, endures despite Ares's death and the Triumph massacre. Now called 'the Rising' by their enemies, they are led by Sevro and operate from the hidden base of Tinos, fielding a Red Legion and cross-Color operatives like the Grays Holiday and Trigg. The Jackal wages a war of extermination against them—kill squads, liquidated mines, and control of the public message—but bombings on the Palatine, strikes on Earth, and protests at the Citadel gate show the spirit of rebellion alive if fractured.
Their great coup this book is the daring rescue of Darrow, the soul of their cause, from Attica.
A cross-Color insurgency marked by Ares's spiked sunburst sigil and the cry 'Break the chains'; fighters range from Red Legion miners to Gray operatives.
The rebellion at the heart of the story; the Rising against Gold rule that Darrow was made to lead.
