The Grand Obsidian Hotel was never just a building; it was a hungry, structural anomaly hidden deep in the Adirondack Mountains. When it was abandoned on Halloween night in 1994, it took four hundred souls with it, erasing them from reality as if they had never checked in at all.
Thirty-two years later, four friends an urban explorer, a journalist, a cameraman, and an anxious skeptic broke through the rusted gates to document the decay. They expected dust, mold, and memories. They found a trap. The moment they stepped into the lobby, the architecture shifted, the exits vanished, and the hotel began to whisper their names. The Last Check-In is a psychological journey into a spatial loop that feeds on human history. As the walls pulse with the heartbeat of the building and the shadows of 1994 begin to hunt, the group must solve the mystery of the "Permanent Inventory" before they, too, become part of the hotel's eternal collection.
