+Humans had always looked up at the skies at night, dreaming of being one with the stars. Yet they never imagined what their dreams had in them.
+
+They ended up getting into space and the revolution that this provoked. With the advent of terraforming technologies, colonists began flocking to the stars en masse. Many worlds where colonized and humanity expanded.
+It was still slow travelling and time was starting to erode humanity's unity.
+
+Then.. Came the great advance in travel. Light speeds where finally broken. This technology spread quickly and reignited the colonization spree. Humans had conquered a great part of the galaxy. Things where hectic though, with mankind fragmented in many factions. A federation was created to attempt to affront this.
+
+Yet, this only incremented tension. Man was too fractured to be weaved together with diplomacy. War broke out, timidly at first, but quickly gathering momentum. Thus began the Great Faction War!
+
+Being the first space-era all out global war, the Faction War brought much pain and misery to humanity. Many plants where annihilated, trillions killed, all in the name of each faction. Mankind started becoming tribal and isolated, seperated by vast space filled with the debris of battleships and smoldering planets. Then came hope at the hand of the Emperor Daedris.
+
+A newly forged Empire began sweeping the factions, dominating with clear military superioriy. Some factions resisted at first, but most saw the only way was to sumbit to the iron fist of the Emperor. Eventually there was only the Empire. Those who helped in the birth of this Empire where given the status of Great House, and the golden age began.
+
+Trade routes where created, patrols where installed and piracy was non-existant. Supplies where being moved all around the Empire and population was booming. Technology advanced quickly and permitted the terraforming of many new planets. All was working well.
+
+Eventually, corruption started to appear, timidly at first, but ended up avalanching. The Great Houses started bickering between each other. Privateers and Pirates started appearing, while the Emperor started to get drowned in burocracy. Terrorism also began to appear by sectors of the Empire not content with their status.
+
+Then suddenly, silence. No one knows exactly what happened, but a gigantic explosion shook the foundations of the universe. The magnitude of the explosion was so enormous that it quickly annihilated many planets, leaving a gigantic void in the center of the Empire. Humanity's birthplace was near the epicenter, and the entire area was covered in a gigantic nebulae. It is referred to as 'The Incident' and marks the end of the golden age.
+
+You find yourself in a universe with a decaying Empire, full of piracy and corruption, shaken to it's very bones by the Incident. However, where there is chaos, there is also oppotunity.
+
+
+
+WELCOME!! To the universe of Lephisto!!
