The "Top Secret" key member of ID.
You descend the inorganic stairs into the basement. The dim staircase, which felt like it would go on forever, comes to an abrupt end.
There, standing alone, was a single door.

You sense a presence behind the door. It seems there is no mistake—this is Guest's destination.
