History of Chagroth Durinhelm

Five years into the War Against the Far Realm, the forces of Erathia suffered their worst defeat. Multiple planar breaches opened simultaneously in the Kirinal Pit, causing a massive explosion that destroyed the fortresses on it's rim an widening it from 20 miles to 30 miles.   All magic in the world failed for 24 hours, the Day of Dispelling. All portals closed. Wards and enchantments everywhere, some that had stood for millenia, ended. When magic came back, the portals reopened and the hordes and armies from many worlds poured out.   Internal fighting amongst the invading forces gave the defenders of Erathia enough time to organize a defense and form a new line.
