Vigrith

In the Aeon of the Champion story series, Vigrith was the single continent of Middle-Earth pre-Sundering, when the Ordering of the Universe by the Pantheon. It is Elva the Mother-goddess who gave Vigrith its name.

Sundering
During the War of the Ancients, Dan'Ariz and the rest of the Sarmatian High Caste agreed to build a portal to facilitate the crossover of Sargamon onto Middle-Earth in order for him to bless them with the arcane power they had always wanted. Tiberian, a senior among the Magi and learned scholar of Dan'Ariz, learned of the reckless experiment his superiors were undertaking and spearheaded a resistance movement, in concert with the night elves, to stop him from endangering everyone. During the final showdown on the Cerulean Plateau, the crossfire between the King and Tiberian was too stressful for the plateau to handle; it was torn apart, blasting Vigrith to pieces and sending pockets of land spinning out of the centre of the planet, while also creating a gaping wound in the planet's surface. Arcane lifeblood glooped out of Middle-Earth, leading to even more destruction and panic.

Nowadays, Vigrith refers to one of the Western Kingdoms. The modern-day night elves and sarmatians are native to this continent.

Trivia

 * Vigrith suffered a very similar fate to Kalimdor in Warcraft lore; both continents were torn asunder during a fierce war.
 * Unlike the Sundering of Kalimdor, Vigrith's sundering did not create a maelstrom. That said, it did leave a major hole in the surface of Middle-Earth.
 * Tiberian said afterwards that he did not have regrets about destroying the Cerulean Plateau, even if it robbed the sarmatians of their power.
