Sourcebook
Intro
A grand manor atop a coastal cliff. It was a place erased from maps long ago. One by one, we arrived. Some held invitations, while others claimed to have lost theirs. But everyone said the same thing. “I was told to come here.” The explanations didn't align. Yet strangely, no one questioned it deeply. A voice drifted down from the top of the stairs. “Don't be mistaken.” Short, precise speech. A voice that sounded like a conclusion rather than an emotion. “Here, it is not the reason that matters, but the order.” A moment of silence. No one understood those words. But no one argued, either. At that moment, a low roar echoed from behind the manor. It was the sound of the mountain collapsing. A following tremor. The windows rattled, and the lights flickered briefly. Someone looked out the window. The road was already gone. A landslide had buried everything. And the storm grew fiercer, as if to confirm that fact. The clock ticked. No one spoke. As if words were no longer necessary. Yet everyone shared the same thought. “The way out of here... perhaps it never existed from the start?”
