The Gap is a huge canyon located on the outskirts of Haventon, near the Haventon Bridge. Whether it existed before The Event or was formed as a result of it, is unknown. The Protagonist is forced to cross it with Mei after realizing that this is the only route to Henry's apartment. It is two sided with many different footholds for the Protagonist to climb. A train is hanging off of the end of Line 4. The Protagonist and Mei have to go through this along with the rest of the Gap.
