The Vanguard Obscura is a colossal, armored spacecraft designed not for war—but for containment. Functioning as a mobile high-security prison, it drifts along the edge of galactic territory, away from inhabited systems. Its vast, brutalist structure is covered in modular containment blocks, security towers, and reinforced hull plating. Red hazard lights flicker across its skeletal corridors, and warning sirens occasionally howl when anomalies are detected.

Instead of a traditional bridge, it uses a distributed AI core to operate autonomously with minimal human oversight. Massive energy shields protect its detention cores, while onboard drone patrols and mechanical enforcers handle discipline.

The ship is controlled by a cold, sentient AI known as Warden Nyx, who was once a human justice official that uploaded herself voluntarily. She has no sympathy, no sleep, and no boundaries. She’s the ultimate jailer.
