Lee Sojin thought five years of containing nightmares had earned him a quiet retirement.

Instead, the Administration falls overnight, the world ends, and his damaged containment base becomes humanity's last safe haven.

With dangerous anomalies roaming free and every death sending him back through time, Sojin begins rebuilding the shattered facility one containment cell at a time. Every rescued survivor, every recovered artifact, and every newly secured anomaly brings civilization one step closer to recovery—provided the next catastrophe doesn't arrive first.
