Infinite Gate
this unusual technology was developed by the Kwa during the early millennia of the galaxy. They used these gates to travel throughout the universe. They created Star Chambers to guard and protect the integrity of the gates, allowing the gates to remain operative almost indefinitely. One of these gates was located on the planet Ova, and the master gate was believed to have been located on Dathomir. When the Witches of Dathomir tried to open their gate, in an effort to escape their captivity, they activated a fail-safe device that shut the Gate down. It also destroyed the Gate on Ova, subsuming the planet and literally sucking it out of existence.
