Playground
The playground, located somewhere in the United States Midwest, is an area that the angels have designated as the sole Earthly gate to Heaven after the Fall. The gate is a special sigil known as Metatron's Cube, drawn into a sandbox. The playground is typically guarded by one or two angels. After the revelation that there are only nine angels left in existence, Naomi chooses to close the gate until Castiel can located Gabriel, and bring him back to Heaven.
