The Coronation Day Battle took place on the full moon of July, 439 HE, the coronation day of King Jonathan IV. Roger of Conté, who had been previously resurrected from the dead by Thom of Trebond, wished to create such a large earthquake that it would destroy all of Tortall. There was quite a few dead from both sides, but King Jonathan and his combatants were ultimately victorious due mostly to the Dominion Jewel.
