Feroxygen

In a future shaped by an intervention meant to stop runaway warming, oxygen begins to rise again and makes ordinary fire a planetary danger. Lia Orta, a forensic ignition cartographer in a high-altitude citadel, investigates an "impossible fire" as Nilo Aram works to keep his lowland community alive through dangerous peat-fire seasons. A parallel timeline follows the people who built the intervention and the choices that made it difficult to reverse. The project combines an ecological science-fiction premise with an investigation; its chapter drafts are still being assessed as the novel develops.

A hard-ecological-SF forensic investigation — an inverted climate catastrophe (too much oxygen, not too little) with the visual ambition of Scavengers Reign and the systems rigor of The Expanse.

The premise reverses a familiar climate-fiction expectation — too much oxygen rather than too little — and gives the investigation a concrete environmental threat. A forensic cartographer reading heat and pressure gradients can make the worldbuilding serve the mystery rather than become an infodump. The dual timeline lets the novel examine how a well-intended intervention can outlast the institutions meant to govern it. Scientific assumptions remain under review; this profile describes the intended premise, not independently validated science.

The project is set roughly 18,400 years after a human climate intervention and uses a working specification involving elevated atmospheric oxygen, high-altitude cities and peat-fire lowlands. The precise physical model, terminology and title/brand identity remain in development review. This is a fictional world specification, not a claim that the scientific model has been independently validated.
