The Tyrancy
The Tyrancy was a interstellar empire covering most of the worlds of mankind, lasting from 6778 AD to 7791 AD and its leader was the infamously brutal (and undying) Tyrant, Orlando Zhu. Born on the colony world of Rehann, his early life was extremely difficult, losing both of his parents at a young age and being abused by employers as he toiled in an under-age factory. He joined the Empire of Humaniti military in its waning days and when the government finally fell apart, he staged a military coup on Old Earth in 6778 AD. Although several other military and civilian competitors tried to take humanity’s' capital from him, the Tyrant held on grimly for nearly a year until a significant majority of the armed forces eventually lined up behind him. He then went on to unite nearly all of human space under his direct rule, an era known as "The Tyrancy".
Living almost a thousand years due to nanotech and advanced whole-body cloning, Orlando Zhu ruled with an iron fist and he also bribed various leading officials with life extension drugs which nearly doubled their lifespans.
Sadly, these officials would die rapidly if they were taken off the drugs, making blackmailing and bribing them extremely easy. During his reign, Zhu was assassinated several times but a new clone would just replace the old one, ensuring governmental continuity and his tyranny. A military genius and brilliant economist, he eventually moved the capital to the jumbo-world Corfu, which was at the time an up and coming economic giant since the world was much bigger than Old Earth and had a far larger population. Eventually, in 7790 AD officials within the government that were continually brutally subjugated by the Tyrant rose up against him and he was killed for the last time. To do this, his half-dozen dispersed cloning facilities were discovered and destroyed, and a new civil war broke out to try and fill the role of leader. Ultimately a advanced AI named "MANN" forcibly took over the reigns of government and ruled for the next 1,000 years, with disastrous consequences for mankind!
