The Wasteworld

10,000 years before the destruction of the old world human civilization was incredibly advanced thanks in large part to the powerful element fosium, which had enough energy to power the world for many years, this was a prosperous time for humanity, scarcity was a thing of the past, people had everything they wanted money, freedom and independence, but although the element was powerful it was rare and in 200 years the time came to look for more fosium, countless space-faring expeditions were conducted in order to find more of the element but to no avail and soon the world was starting to run dry on fosium as a result countries started to wage war, this was the start of what is known as "The Great War".
