No one knows who built it. No roads lead to its entrance, no records mark its existence. Some say it’s a remnant of an abandoned Federal Reserve outpost, a forgotten institution meant to secure something far more valuable than money. Others whisper that it’s a waypoint between realities, an anchor for things that don’t belong here.Travelers who dare to approach find the building locked, impenetrable. Those who linger claim they hear murmurs leaking from the walls, old voices discussing transactions that never took place. A ledger of debts no one remembers owing.
