Within the dark seams of Runeterra, the demon Evelynn searches for her next victim. She lures in prey with the voluptuous façade of a human female, but once a person succumbs to her charms, Evelynn's true form is unleashed. She then subjects her victim to unspeakable torment, gratifying herself with their pain. To the demon, these liaisons are innocent flings. To the rest of Runeterra, they are ghoulish tales of lust gone awry and horrific reminders of the cost of wanton desire. Evelynn is a vicious and cruel creature that hunts for prey without mercy. In the beginning of her existence during the Rune Wars, Evelynn was a thoughtless entity that hunted for pain to satisfy her hunger. Once the war ended, Evelynn decided to attract her prey by using a sensual form. Under this persona, Evelynn is charming and flirty towards her victims, manipulating others towards her doom. She prefers those that live happy lives, and then brings them to the peak of ecstasy so that their agony is more intense, relishing in her cruelty.
