Valley of the Sun
There weren't always Dragons in the Valley. There are few today who were alive during the Awakening, and even fewer still old enough to remember what really happened. The stories they tell have minor discrepancies; What caused the Dragons to arise, where they first began their War of Human Extermination, how many Dragons are left. Each remaining settlement, every band of human remaining tells the same beginning: It has been nearly one hundred years since the Earth split open, and Humanity's grim obsession with fighting monsters finally came to fruition. The epicenter of this catastrophe was called "The Valley of the Sun." A dry, hot, miserable place that housed one of the most populous cities in the country. Over eight million people spread across this vast basin. Their homes kept cool all summer long with electricity powered by a hydroelectric plant a hundred miles away, every lawn a lush, verdant green thanks to water siphoned from every available well and mountain spring. Water was even trucked in to maintain this illogical and farcical city. Yet it thrived. Several of the largest universities were in this place, globally recognized restaurants were filled every night, and there was no shortage of museums and cultural centers.
