Gemini

Gemini is an Incandescence world. It was the fifth world to encounter the Plague of Utopias. In all ways other than the following, it can be considered identical to our Earth.
==Superpowered Twins==
In the fifties, twins started receiving superpowers when they turned sixteen. Superpowered soldiers and policemen are now relatively common; both supervillains and superheroes exist, but are much rarer, as they are generally considered nonviable careers. The United States has instituted mandatory Gemini Schools for high school age twins, which despite requiring monitoring and registration have so far proven non-dystopic.
==Yellowstone==
More recently, the supervolcano under Yellowstone erupted. Most of the Lava Creek Tuff was evacuated, and much of the rest of the world was swamped with refugees and operating in emergency mode. The chaos was mitigated by the arrival of the Plague of Utopias, which has been summoning angels and demons to provide emergency supplies and return the affected land to a habitable state.
