A Prison of Souls
The Blade of Lost Souls, known by its creator as the “Ourobouros Blade”, serves as both a prison and a powerful weapon. Originally forged to contain the rapacious demon of war known as Kuzuru. However this soul binding came at a terrible cost, while the demon was trapped within the blade he was not completely subdued. The sword become a sort of "soul sponge" and absorbed the soul of anyone that was unfortunate enough to be felled by its blade. Without a host the demon inside will call out to nearby warriors and offer them immortality and unparalleled skill in return for their soul, a deal that all too many gladly accept.
Over time this constant bloodshed has resulted in the blade acquiring a tempest of souls. While the majority have lost their individuality a few particularly strong souls can maintain their identity. Before the Omniverse this individuality never more than the occasional voice inside Renji's head, but now the sword's ability to contain these souls has been diminished greatly and the most spirited of souls can take temporary control of the poor man's body.
Kuzuru [spoiler]
Less of an individual and more a force of nature, Kuzuru was birthed the moment primordial man dashed his brother's head open with a rock. The demon exists as the culmination of every act of bloodshed or violence mankind has ever wrought upon itself. In an attempt to squelch his affect on mankind he was imprisoned with the Ouroboros Blade.
Thanks to the magic of omnilium he was able to reconstruct the very nature of his prison and switch places with Renji.
At heart Kuzuru is a showman and will go out of his way to turn things into a spectacle, after all there's only so many ways you can kill a man before the whole thing becomes a bit boring. He chases novelty and often picks up various hobbies to try and entertain himself, unfortunately bloodshed seems to be the only thing he is competent at as he is seemingly unable to become proficient at anything besides combat. He is rather sociopathic, only caring for people as one would care for property. He sees the Omniverse as the ultimate playground, a conglomeration of the strongest warriors just ready to be conquered.
Renji Kiyomasa [spoiler]
[/spoiler]Born an orphan and adopted by a dojo dedicated to the Kiyomasa style of swordplay, Renji is the current wielder of the wicked Ourobouros Blade. Raised by skilled swordsman Renji quickly adopted a warrior lifestyle. An incessant desire for perfection in every aspect of his training led to him becoming a star pupil. Every breath and every action was taken to further his progression as a splendid swordsman. The young Renji Kiyomasa, having taken the swordstyle as his family name, became the greatest student among his hundred man class, a feat which was no small accomplishment. One day, growing somewhat arrogant, Renji challenged his master to a duel, confident in his ability to beat the old man. The fight lasted all of three seconds, with a blindingly fast strike Renji’s master had disarmed him and scored what would have been a lethal blow had they not been using practice blades. After suffering an embarrassing defeat in front of his peers, the dejected swordsman ran into a nearby forest to lick his metaphorical wounds.
Inside the forest Renji felt an almost imperceptible pull towards an almost hidden cavern deep within. Smooth, wet walls formed a dome and in the center a shaft of light pierced the center of the cave. Inside, illuminated by the aforementioned shaft of light, sat a polished pillar of stone, and on top of the pillar sat a katana sheathed in a blood-red scabbard. Renji carefully shuffled through ankle deep water towards the weapon. His blood chilled. Upon gripping the blade the young boy felt an impossible surge of strength. The hot shame of his previous defeat was washed away with the sudden clarity that the blade offered, and to keep it he only had to trade away his freedom. This deal he gladly accepted binding his soul to the weapon, and subsequently the demon hiding within. With his new-found power Renji returned to his dojo and slaughtered every last member, unable to resist the intoxicating bloodlust that he now felt.
Rou Maxwell [spoiler]
[/spoiler]The very first wielder of the cursed Ourobouros blade and the first wielder to be swallowed by its wicked powers. Rou stumbled upon the cursed weapon during a grand battle, one in which he was merely a foot soldier. Caught on the wrong end of a cavalry charge Rou was mortally wounded and left to bleed out. Around him the din of battle raged and all he could feel was the cold grip of death. It was with what should have been his final breath that time seemed to freeze around him. Almost as if stepping between dimensions he entered a fugue state. His body was weightless and without effort he climbed to his feet. Before him towered a red-skinned demon, clutching a red-hilted blade and offering a second chance at life. Without a second thought he accepted the bargain and agreed to be the first true wielder of the Ourobouros Blade. As if someone had pressed “play” on a video recording the battle resumed and Rou was left with the wicked blade in his grip. The scent of blood and the sight of carnage illicited a primal reaction from the lazarusian soldier. It was on this day that he became a god of war, wading through his enemies like a butcher carved through carcasses. Overnight he became a tireless avatar bent on bloodletting, a demon of war.
It is unclear as to how his reign ended, but a few things are certain. One, he was killed by his own blade, and that he lived for several eons before his death. Now he serves as a pragmatic guide within the prison, offering Renji advice from time-to-time.
