Portal 101
From Create Your Own Story
Portal 101 holds the worst thing in the universe. Panicking, you open your Medkit and feel around for a few pills to ease your fears. After swallowing them, you find your brain flowing with fierce, positive energy. Wielding mighty telepathic powers, you dispel the demons dwelling within this strange dimension and transform it into a paradise of pink skies and rock-candy mountains. Of course, the rock-candy mountains attract giant flies, but the flies are strict candy-vores, so that's ok.
You rule here in your perfect dimension for 1000 years. Then you decide to explore other portals nearby.
