[Champion Concept] Alatar - The Plague's Will
Lore A Noxian experiment that failed resulted in the lives of a family to be ended. Without a doubt they all died, but they did not all stay dead. Alatar was 7 year old child when he saw black mist flying at him, that was his last memory. The magic powder seeped into the bodies of the fallen family, for years on end. Eventually it managed to disintegrate all but one corpse, that one corpse was Alatar. Alatar awoke with an unfamiliar feeling, a feeling of power and a feeling of pure hatred. The memories that happened to his family after they died all were stained into his brain. He screamed in anger at seeing what was done to them, but no sound came out. Instead the powder that had taken his lives so many years ago, fell from his powder melting the ground it touched. Alatar ran in fear of what was happening but a trail was left behind him, burning the ground. He ran out of Noxus and fled into a distant cave. In the cave, voices of his dead family spoke to him, they wanted him to return to them, be one again. These memories tormented him for what he thought was a mere week, but it was 20 years. He eventually gave in and heard a voice that promised to end the insanity of the dead. It tempted him and eventually he gave in. The black powder that he feared so much began to corrupt his very being. It took over his mind, controlling all of his desires. With that he set out to do as what was intended from the very beginning.
