Revolutions is written and narrated entirely by Mike Duncan, previously the creator of The History of Rome, with no interview segments, co-hosts, or additional voices in the sampled episodes. Each episode is structured like a documentary history — quotations, timelines, and in-universe source references — applied here to an invented conflict rather than a real one. The arc tracks the final year of the fictional Martian Revolution: Omnicorps' nuclear bombing of the city of Elysium, the tiered trials of Earthling detainees and 'earthworm' collaborators, fleet battles at Lunaport and the asteroid belt, and a coup and countercoup within the revolutionary Triumvirate. Recurring figures across episodes include Martian Guard commander José Calderón, his rival Alexandra Clare, naval officer Booth Gonzales, constitutional author Marcus Leopold, and videographer Zhao Lin, whose competing accounts of events drive most of the political conflict. The show repeatedly returns to how revolutionary tribunals weigh evidence versus mob pressure and perjured testimony, how factions turn xenophobia against Earth-born residents into policy, and how a military occupation collapses once its outside support disappears. The presumed audience is listeners already familiar with Duncan's nonfiction seasons on real revolutions, since this arc consciously mirrors that format and pacing while being explicit fiction. It also suits listeners of narrative, analytically-paced alternate-history or science-fiction audio who prefer restrained narration over dramatized dialogue. Production in the sampled episodes is straight narration without dramatized voice acting or music cues, keeping the same measured tone used in the podcast's historical seasons. The season concludes with the Republic of Mars adopting a Second Constitution guaranteeing equality regardless of birthplace, closing the fictional revolution the way Duncan's nonfiction seasons close real ones.
