Mysterious underground passage
In Occult Academy, when the protagonists explore the mysterious underground facility of the academy, they pass through a dark tunnel entrance. The walls are covered with concrete and metal pipes, and under dim lighting, the air is filled with dampness and mustiness. This was once the site of a secret experiment, with rusty iron doors and warning signs remaining at the entrance.
