Blacksite Helios
Framed and buried in an asteroid blacksite, three prisoners must escape Helios before the conspiracy erases them for good.
About this adventure
Helios Penitentiary is a maximum-security prison carved into a hollow asteroid, where rotating cells, predictive surveillance, and corrupt officials turn every alliance into a gamble. As lockdowns tighten and buried evidence points to a larger operation disposing of political liabilities and military secrets, escape becomes the first step toward exposing who engineered the frame-up and why. Play as the disgraced military strategist hunting the truth behind his ruined command, the razor-sharp engineer who knows failing systems and hidden networks, or the forensic psychologist who can read lies, fear, and the cracks in Helios's manufactured reality.
Prologue
Beyond the reach of law, beyond the coils of charted space, lies Helios Penitentiary. Carved into the heart of a hollowed asteroid, the prison is a tomb of white corridors, flickering surveillance, and the silent screams of the forgotten. Here, alliances are currency, secrets are weapons, and every breath is a gamble against the crushing vacuum and the watchful eyes of the Warden. A new arrival has upset the delicate balance of this fabricated world. Framed for crimes unseen, buried alive in a prison designed to erase identities, this inmate is more than just a number. Whispers echo through the cell blocks, rumors of a conspiracy that reaches far beyond Helios, a truth buried deep within the asteroid's core. Escape is the only answer. Freedom is the first step. But in Helios, the path out is paved with lies, and the only certainty is that someone wants this truth to remain buried.
