Trolls have never been well-regarded beings of Valoran. Generally speaking, they are barbaric, cannibalistic, and sneaky. They are creatures relegated to the murky recesses of the world, hidden away from most intelligent beings. Despite their maleficent natures, however, the Ruhgosk never deserved the grisly fate that was visited upon them. Generations ago, a twisted necromancer known as Hakolin the Bonecrafter attempted to enslave the Ruhgosk tribe. These trolls are considerably more genteel than their ill-mannered brethren, although still uncouth by human standards. The Ruhgosk fought tooth and claw against the necromancer, ultimately driving him from their land. As a parting gift, Hakolin afflicted the trolls with a leprous disease, forever cursing the members of the tribe. The leprosy would have rotted their flesh away to nothing were it not for the trolls' natural ability to regenerate. Caught forever in a hideous rotting state, the Ruhgosk endured their curse while desperately in search of a cure. They never found one.
A wise Ruhgosk shaman learned that he could magically bind the disease to a single troll, provided that the troll could bear the weight of the entire tribe's curse upon himself. However, there was no such troll...until the birth of Trundle. His ability to regenerate was so profound that it appeared as if he did not carry the disease. As Trundle grew, he came to understand his gift and what it could do for his people. When he came of age, he took the curse from his tribe in a baptism of searing agony. Through the shaman's ritual, Trundle became a horrifying creature whose flesh constantly sloughs off his body, only to be re-grown in an unremitting cycle. He has joined the League of Legends in hopes of eventually finding someone who could dispel the heinous curse completely.
