the entrance to Heaven.
The Navel of the World contains a large ivory tower that holds Heaven’s Gate at its centre, and a long path leading up to the tower. It is rarely visited by surface dwellers, but as a safety precaution to prevent people from discovering the gate, hundreds of Themis Traps guard the pathway.
In Monster Girl Quest Paradox, Sonya tells Ilias that the Navel of the World was consumed by the Tartarus rift during the Great Disaster 30 years ago, making Ilias questions if it is even still possible to access Heaven. The answer is yes, as the remainder of Heaven formed the newly discovered Snow Continent.
- The tower is never actually shown on-screen.
