The Ringpullworld, named by Tegan, was the micro-universe contained within a can on the planet Must. The inhabitants of the universe were called "Ringpullworlders," and were separated from the rest of the cosmos due to the actions of one of their species attempting to invade and conquer others. The races of the cosmos that imprisoned the Ringpullworld did so using the power of dimensional transcendentalism, given to them by the "Dark Ones" from their "twilight dimension."
