The land know as the Shadow Isles was once a beautiful realm, but it was shattered by a magical cataclysm. Black Mist permanently shrouds the the isles and the land itself is tainted, corrupted by malevolent sorcery. Living beings that stand upon the Shadow Isles slowly have their life-force leeched from them, which, in turn, draws the insatiable, predatory spirits of the dead. Those who perish within the Black Mist are condemned to haunt this melancholy land for eternity. Worse, the power of the Shadow Isles is waxing stronger with every passing year, allowing the shades of undeath to extend their range and reap souls across Runeterra.
