When the first modern humans evolved on Earth, a meteor struck. When the meteor hit the atmosphere a strange thing occurred. A wormhole formed, taking 50% of all life on Earth with it, into another dimension. Time here was different. For every 1,000 years there, only one year has passed here. All the life was scattered across one of its universes. Over time they adapted and evolved quicker than here. Their technology looked primitive compared to what we have. They called themselves Gemmianites.
