The Reckoning
An event (see: Timeline) which takes place shortly after the campaign The Sword of Frost from Heroes Chronicles (precisely on 08-04-1177), a massive explosion created by the clash of Gelu's Armageddon's Blade and Kilgor's Sword of Frost. It starts a chain of thousands of earthquakes and volcano eruptions, which in turn destroy the planet itself. However, portals open to Axeoth and many people escape from the dying world helped by the Angels.
