Luci was very excited. After hundred thousands of years of sneaking around and hoarding, his efforts were finally going to pay off. Luci had finally been promoted to a type of angel called a Grim Reaper.
In Luci's new job he would guide a person's soul after death to the Alpha and Omega Hall. In this Hall the soul would get Judge by an all-knowing complicated System to determine his/hers new destiny and rebirth. Before the soul gets placed into a new life, it is cleanse of its previous destiny.
A soul's destiny is a person's experience and potential before death. When a destiny is cleansed from the soul's it is flushed back into the limitless cosmos to be recycled.
Luci didn't always want to be Grim Reaper. No, he started out as a Surgeon of Destiny. He would use a scalpel made from profound technology and magic. He would swiftly operate on souls to remove their destinies leaving only pure souls ready to be implanted with new destinies. These destinies would be amazing, terrible or just ordinary as dictated by the System. Luci always did his work in the Operation Temple flawlessly without ever questioning his existence. That was the case before he somehow offended a supervisor and was demoted to the lower angelic rankings, Purifier.
Purifier were glorified janitors. While still angels, they would clean the Alpha and Omega Hall. Whenever he would see his former colleagues they would never stoop so low as to acknowledge him. As he would empty out the containers in which the destinies were placed after surgery, Luci realize he was the same as them before his fall from Grace. The other Purifiers would also shun him remembering his former attitude.
Without anyone to communicate with Luci grew very lonely. Forming a distance and dislike of his own race.
But in this isolation Luci discovered something very interesting while shoveling the destinies into the cosmic whirlpool that lead to infinite and forever. Luci noticed sometimes a destiny wouldn't be scattered into the limitless cosmos, but would remained whole. He also discovered if he held onto a pieces of destiny he would be transported into the soul memories. This became Luci's only escape.
Every day he would 'live' a new life and 'experience' a new discovery. His world view changed drastically after that. Luci would no longer recycled all the destinies, instead he would keep a few fragments so that he could return to them again and again. Luci would 'see' worlds of great battles between humans and monsters. Gods and Demon experiencing love and lost. Unbeknownst to himself he had started to accumulate a destiny of his own.
Amazing sciences that let mortals explore their galaxy and encounter many alien races. Sometimes good and sometimes bad. Acts of profound magics performed by immortals for good and evil.
Sometimes he would 'live' as an evil being plotting and rampaging his/her world for pleasure or revenge. Other times he would be a saint granting blessings and miracles to help make a better world. Luci would specifically like the lives where he could swing a sword and strike down his enemies by the hundreds.
Longing grew inside of Luci. He was no longer satisfied 'living' second hand lives, a plan was made.
The Alpha and Omega Hall and System had existed before time. It was made from powerful science and profound laws. The whole universe was subject to these laws. Since time started many races strived to understand these laws and break free from them. None of them ever made it close. Luci would keep these destinies from sages to learn from.
Luci couldn't defy the System, but maybe it could avoid it. Using the genius from countless unorthodox sages put him in unique position to do the unthinkable.
As a Purifier Luci was granted access to many locations within the Alpha and Omega Hall. Turns out the System can't control a person's free will after rebirth. It could only set the soul on a path to reach it's potential. That's when Luci found out about Grim Reapers.
As a Surgeon of Destiny Luci never encountered the Grim Reapers as there was an angel who would take the soul from the place of Judgement to the Operation Temple. Grim Reapers would roam the cosmos collecting souls bringing them back to the System. Most Grim Reapers would first remember the time and place of future deaths to be able to receive these soul.
Grim Reapers never stayed in one place for long before moving on to the next predicted death not caring nor understanding the world they pass through. Most Grim Reapers would be away from the Hall for eons at a time collecting lost souls that died in unpredicted ways. The unpredicted deaths only accounted for 0.00000001% of all deaths. This is in no way a small number when the whole Limitless Cosmos is concerned.
Luci knew that this 0.00000001% was his tickets to finally live real lives.
Luci schemed and plotted his way into a Grim Reaper position which wasn't that hard to do considering that most angels preferred to stay in the Alpha and Omega Hall.
Now was the time to use the knowledge from countless Necromancers, Shamans, Spirit Cultivators and Gods of Death. Throw in the many profound laws he was able to understand from the Alpha and Omega Hall. Luci was finally ready.
It took Luci many millenniums before he found a world to his liking. He had passed traveled through a corner of the cosmos were the beings didn't really have shapes.
This new world was called Orors. Orors existed connected to several worlds by Bridges made of time and space laws of different size. These worlds existed under similar laws of magic, sword, nature and gravity so the inhabitants could use the Bridge to traverse these worlds and their lands.
Luci had pondered this for a long time and had decided that he needed to experience life like the inhabitants. So he would seal away his memories and enter a young recently deceased body. In other words the best way to get the most out of this chance. Luci was ready to feel real love and real hate.
Luci chose Bartholomew Straus.
