ERT! is a verse that generates TONS of electricity between Riverses, electrokilling anything and making it uninhabitable. There are wires connecting the Riverses.
The wires generate thousands of times more electricity than the main verse area, and they have 8 holes and a storage area. The storage area stores electricity and sometimes they send it out and they also can open and close holes, purposefully letting out electricity into the ERT!
These planets are rogue planets because they don’t have stars. They are scorched and burn up anything that touches them, and they also contain huge amounts of electricity. These planets are uninhabitable, so nobody lives there.
