Lore:
There is a temple hidden in the mountains between Noxus and the Tempest Flats, where the secrets of an ancient and terrifying sorcery are kept. The area surrounding the temple is littered with the exsanguinated corpses of those who have mistakenly wandered too close. These served only to pique the curiosity of Vladimir, when – in his youth – he trekked through these mountains during his flight from Noxus. A day earlier, the teenaged Vladimir had brutally murdered two boys his age, for no better reason than to enjoy the intoxicating scarlet bloom that surged forth. He realized immediately that he would never be able to suppress his murderous desires, and if he remained in Noxus, his foul deeds were sure to catch up with him. Without hesitation, he abandoned the city-state, and journeyed south.

The trail of bodies led him to a crumbling stone temple. Inside he found an aging monk who appraised him with eyes of pure crimson. Vladimir surprised the monk by returning the wicked gaze with zeal. Recognizing the boy’s sinister craving, the monk taught Vladimir how to manipulate and control the fluid of life, often practicing on passing travelers. When it came time for Vladimir to learn the final lesson, the monk warned that failure would result in death. Vladimir did not fail, but success bore a grisly surprise. During the ritual, every drop of the monk’s blood was drawn from his body and fused with Vladimir’s, imbuing him with his master's magical essence, and that of every hemomancer before him. Left alone and suddenly without purpose, Vladimir resolved to return to Noxus, demanding enrollment in the League to prove the supremacy of his craft. When the Noxian High Command observed the gruesome fates which befell the palace guards, they elected to avail themselves of Vladimir’s unsavory talents.

Lore:
When the prophet Malzahar was reborn in Icathia, he was led there by an ominous voice which thereafter anchored itself to his psyche. From within, this voice bestowed upon him terrible purpose, and though Malzahar was no longer tormented by its call, the voice did not cease its unrelenting summons. This baleful beacon's gentle flicker -- now fastened to Runeterra -- drew forth a putrid beast that ambled across a threshold it did not understand, widening a fissure between spaces which were never meant to meet. There amongst the haunting ruins of Icathia, Kog'Maw manifested in Valoran with unsettling curiosity. The spark which led him to Runeterra teased him still, urging him gently towards Malzahar. It also encouraged him to familiarize himself with his new environment, to the stark horror of everything he encountered on his journey.

The enchanting colors and aromas of Runeterra intoxicated Kog'Maw, and he explored the fruits of the strange world the only way he knew how: by devouring them. At first he sampled only the wild flora and fauna he happened across. As he traversed the parched Tempest Flats, however, he came upon a tribe of nomads. Seemingly unhampered by conventional rules of physics, Kog'Maw consumed every nomad and any obstacles they put in his way, amounting to many times his own mass and volume. The most composed of his victims may have had time to wonder if this was due to the caustic enzymes which stung the ground as they dripped from his gaping mouth, although such musings were abruptly concluded. When his wake of catastrophe reached the Institute of War, an enthusiastic Malzahar greeted him with an enticing prospect: taste the best Runeterra could offer…on the Fields of Justice.
