I know where she hides the Tenno heart; A womb in the sky, forbidden to my kind, but where you will take me.
The Void is a mysterious realm of extradimensional space, where the laws of physics hold little sway. It is the source of many mysterious phenomena, such as void storms, and the origin of the Tenno's powers.
As a Star Chart location, the Void is characterized by the presence of Orokin Towers, gleaming white and gold structures built by the Orokin for unknown purposes. These towers are of immense interest to the major factions of the Origin System, who desire the vast treasures and Orokin technology hidden within.
Unlike other planets whose entirety can be accessed from a single entry node, the Void is divided into four different set of nodes, each set separate from each other that must be accessed from four different planets (Phobos, Europa, Neptune, & Sedna).
