A colossal space colony designed as a maximum-security prison, ominously floating in the vast darkness of space. Its structure is massive and fortress-like, made of dark, unyielding materials reinforced with glowing energy barriers. The entire colony is surrounded by rotating defense rings bristling with heavy weaponry and patrolling warships to ensure no escape is possible. Inside, the atmosphere is oppressive and foreboding, with dim, flickering lights casting eerie shadows along cold, metallic hallways. Towering cell blocks house the galaxy's most dangerous criminals, each cell secured by impenetrable force fields. The command center, a dark and fortified hub, monitors every corner with advanced surveillance systems. The colony is encased in a protective energy dome, making it completely jailbreak-proof. The surrounding space is desolate and hostile, further emphasizing the inescapable nature of this grim and powerful facility.
