Site Nox is the final world in Arkanoid vs Space Invaders.
Purpose[]
Site Nox serves as the gateway (or at least one of many) between the Invader Dimension and our world and was used to stage the attack against humanity.
Appearance[]
The cities are constructed out of purple, stone cubes, with strange symbols on each side. The nature of this technology seems to have some connection to the invaders, and the inhabitants may have used their power before their downfall.

Backstory[]
Site Nox was abandoned by whatever civilization previously inhabited it for unknown reasons. It is the only civilization not connected to the current humans other than the Antellans, so its destruction may have something to do with the Prehama War.
