At the height of civilization, Thea's sprawling mega-cities stood as monuments to human achievement. Then came the Darkness — a cataclysm that shattered society and claimed billions of lives. In the chaos, a secret network of underground shelters became the final refuge for the few who survived. Project Thea, the last remnant of the Ostoya mega-city, now stands as sentient-kind's final hope. As its sole guardian, venture into the treacherous Wastelands to scavenge resources, confront roaming threats, and guide the Project's growth. If it falls, civilization falls with it.
