"My brother has become hollow. Full of rage, but empty." - Nasus, the Curator of the Sands
On a faraway world, Renekton was born a member of a race of bestial guardians created to serve as the rulers and protectors of their people. Alongside his brother Nasus, Renekton oversaw the upkeep of the Great Library, which served as both a vault of ancient knowledge and the repository of the teachings of the Cycle of Life and Death.
While the enlightened Nasus taught those scholars who came to study, Renekton served as the Great Library's gatekeeper. He could sense the true natures of those who sought Nasus' teachings, and he sent away those with dark ambitions. Over time, however, his repeated exposure to this evil infected his mind. He grew furious with the malevolence in the hearts of men, and as he descended deeper into madness, he discovered he could quell the fury by cutting the evil from the men who possessed it. Unfortunately, the relief was as short-lived as the subjects, and the 'butcher's rage', as it came to be known, would resurge even stronger.
Consumed by his anger, Renekton turned on the one being who could defeat him - his own brother. Nasus pleaded with Renekton to see reason. Realizing that he was beyond redemption, the despondent Nasus valiantly struck down his wayward sibling. Defenseless, Renekton waited eagerly for death's release. It never came. He was spared when summoners from the League of Legends claimed his brother. Caught in the wake of this powerful spell, Renekton tumbled for what seemed like ages between realities. When he finally emerged, he fell deep into the sewers of Zaun.
Insane with fury, Renekton languished in his newfound home, driven senseless by his rage. That is until, by happenstance, he caught a familiar scent in the air. Believing that the familiar scent would guide him to the solace that was fading from his memory, he traced his brother to the Institute of War.
The bestial creature charges into the hallway, his head turning erratically from side to side as he seeks his target. The scent that he has been relentlessly trailing all the way from Zaun has brought him to the Institute of War. The unmistakable musk saturates the Great Hall.
Erupting with fury, Renekton drops down to all fours, sending his enormous weapon crashing to the marble floor. He darts around the room to trace the origin of the scent. There is a frightening madness in his gaze, and his every movement is explosive.
Suddenly, he straightens up, snatching up his blade in a single movement, and charges recklessly into double doors framed by a stone archway. The creature does not reach out to part the doors; they simply burst open from the sudden impact of his entire body. Renekton doesn't lose his stride - not with the promise of his prey so unbearably close.
What the creature does not know is that the unrefusable summons that took away his brother was actually meant to target Renekton.
Renekton stumbles as a wave of vertigo washes over him. The floor drops out under his feet, and after a sickening moment of freefall, he finds himself back on solid ground. The creature rapidly blinks his eyes to clear a filmy haze that swirls around him. Taking a hesitant step forward, he emerges out of a pillar of light and finds himself on a raised stone platform overlooking an unfamiliar forest. The smells of trees, burning torches, and magic tinge the air. He surveys his surroundings, clearly puzzled by how he came to be there. The sounds of struggle can be heard far off in the distance.
Suddenly, his brother's unmistakable scent drifts near and curls around his nostrils. Renekton instinctively launches himself forward, his legs pumping wildly down an open path leading into the forest. His elongated jaw hangs open, exposing rows of wicked looking teeth dripping with anticipation. The blood boils in his veins, bulging through his skin in spidery patterns that run up and down his massive arms.
The creature turns the corner to find Nasus towering over a pool of ineffectual minions. Clad in shining gold armor, his brother expertly spins a staff over his head, unleashing a spirit flame towards the minions. The ground erupts with energy, the magic radiating in a brilliant shimmer as it consumes the small creatures.
But Renekton sees none of that. All he sees is his reckoning.
Renekton springs at Nasus, mowing down the minions who have the misfortune of being in his way. The sudden appearance of his long lost brother barely registers in Nasus' mind before the enormous curved blade comes whistling through the air, aimed squarely at his neck. Nasus narrowly manages to dodge the attack, disappearing in a Flash of light and re-emerging a safe distance away.
Renekton charges forward, slashing wildly with the giant blade. Nasus deflects the blows with his staff, slowly being knocked back with every attack.
"Brother, stop! What are you doing here?"
A grin snakes down the length of Renekton's face. "Carnage!"
Renekton crouches for a split second, and then leaps upward with blinding speed. Spinning in mid-air, he slashes his curved blade in a vicious arc. This time, the blade connects with flesh. Nasus' body falls to the ground, and Renekton stands over him, savoring the final moments before he destroys his brother.
In a beam of light, his brother's body vanishes.
Renekton frantically tears at the ground where his brother's body had just been, his claws ripping the dirt path. He twists around furiously, but the forest around him is deserted. A guttural roar erupts from the depths of his being.
The creature catches his brother's scent again and takes off in a dead sprint down the open path. In the distance, he sees Nasus appear on a platform similar to the one that had brought him here. A growl rumbles from his throat as he charges forward. Three defenders appear suddenly at the base of an intimidating tower at the top of the steps, outfitted with wicked weapons and grim expressions.
Renekton bowls through them, his blade deflecting bullets fired at point blank by a buxom redhead. A bulky minotaurslams the ground and a curiously large armadillo drops down on all fours to defend against the attack, but they are no match for the crocodile in bloodlust. The defenders are knocked aside in Renekton's mad dash for Nasus.
The creature charges up the steps, flying onto the platform with enormous momentum. Nasus reaches out to hold up his palm, as if to stop his brother, when suddenly a bright ray of light shoots out, engulfing him in an agonizing fire.
Renekton immediately succumbs to the darkness.
The creature awakens in a dark room, sprawled on a frigid stone floor. A group of cloaked magicians stand with their hands outstretched in a circle around him. They murmur strange words under their breath, ensnaring him in a glowing net of magic.
When Renekton's vision clears, he sees his brother staring dispassionately at him from across the room. Renekton snarls, throwing himself bodily towards Nasus, but the magical chains that bind him hold firm. Nasus gazes back for a long moment, his expression unreadable. Then he turns and steps into a lighted platform.
Before he disappears, Nasus speaks. "It seems that the time to settle our conflict is yet to be determined. Goodbye, brother."
Throwing his head back, Renekton lets loose a roar that shakes the foundations of the room. The violent rage caused by being so close to his brother and utterly unable to destroy him consumes him.
The summoners standing around the creature don't ask the standard questions. The League finally has its chosen brother.
