In 24 CLE, yordles from Bandle City discovered the continent of Nyroth using their newly established lunar observatory. Perhaps chief among these would be the appearance of Champions, remarkable individuals with abilities unrivaled by any save the legendary rune-empowered warriors of old. In the aftermath of the Rune Wars, wild magic has spread across Valoran, giving rise to strange new phenomena. Only the founding of the League of Legends, with its concomitant restrictions on the use of rune magic, averted this apocalyptic fate. The Rune Wars so damaged the arcane foundations of Runeterra as to threaten total planetary destruction. During the Rune Wars, it was used to obliterate entire armies, split mountains, boil seas, and transform mortals into beings of godlike power. Rune magic is more powerful than ordinary magic by orders of magnitude. Rune magic is that most dangerous kind of sorcery which utilizes runic inscriptions to manipulate leylines, and in some cases even to rupture them and channel the full force of the magic they contain. Most magic operates by harmonizing with the planet's natural flow of energy. Where leylines intersect with sufficient intensity, nexuses are formed, amplifying and "tinting" the thaumic energy in remarkable ways. The pattern of energy flow created by these leylines generates a complex arcane topography, and magic can be used to harness this energy and direct it according to the mage's will. Runeterra is suffused by magical energy, which travels along conduits known as leylines. Some speculate that, without the Rune Wars and the founding of the League, the nations of Valoran might have considerably less cause (and perhaps less ability) to interact. Valoran is a highly interconnected place.
