Navel of the World

The Navel of the World (世界のへそ Sekai no heso) is the entrance to Heaven. As the name implies, it is located in the very center of the world; the center of Sentora. It is a long garden-like pathway consisting of a large ivory tower that holds Heaven’s Gate at its center. It is generally unfrequented by all surface dwellers, but as a safety precaution to prevent people from discovering the gate, hundreds of Themis Traps guard the pathway.

Despite hosting a "huge ivory tower", the tower itself is never actually seen.
