Day of Reckoning is a comprehensive fan expansion for Heroes of Might and Magic III as a continuation of the classic official expansions and akin to Horn of the Abyss. The project aims to complete the story of Heroes III by introducing elements tied to the Reckoning event, the cut Forge content, and filling story gaps. In addition to other features, Day of Reckoning is set to introduce three full new factions: Palace, Grotto, and Forge.
