The sterile hum of the Chronos-Synth module was a familiar lullaby, a stark contrast to the silent, suffocating reality of Neo-Cairo’s arcology 7, a city built upwards into the perpetually smoggy sky of 2342 CE. My name is Dr. Aris Thorne, and I am, for all intents and purposes, a deep-time ecologist. My mission: to witness, to record, to feel the pulse of Earth’s ecosystems over the last billion years. We live in an age where our home planet is a fractured memory, its natural harmony replaced by engineered survival. Understanding the grand narrative of its past transformations, its resilience, its fragility—this isn't just academic; it’s a desperate search for a forgotten blueprint, a ghost in the machine that might just save us.
