Star Palace

The Star Palace (天星宮) also known as Heaven (天界) is the Place of Beginning (始まりの場所) where Veldanava first awoke during the dawn of creation.

It’s a World isolated from all other universes yet adjacent to them at the same time. The only ways in are to have a special Key (鍵) that allows for inter-dimensional travel to and from it at will or to access it through the Heaven Tower guarded by Dagruel.
