Might & Magic Heroes VI takes place in the 564th year of the Seventh Dragon* (approximately 400 years before the events of Might & Magic Heroes V), during the time of the second Blood Moon eclipse and the rise to power of Kha-Belekh, the future Demon Lord.
The legendary Archstrategos of the Archangels, killed during the War of the Ancients, is resurrected. Under the guise of preparing for the demon invasion, he seeks to restore his power and conquer Ashan, while simultaneously destroying his ancient enemies. However, he underestimates the simple human dynasty of the Griffons...
Heroes VI tells the story of the Griffon family at a time when they were still Dukes of the Holy Empire and had not yet ascended to the Imperial Throne (as in Heroes V and Clash of Heroes). The Duchy of Griffon is located in the east of the Empire, in an area that corresponds to the Slavic countries in our world.
The founder of the dynasty, Duke Pavel, was a devout servant of the Light and a trusted commander of the Emperor. He fell defending his land from an armada of demons summoned by the death curse of a desperate enemy. Pavel held out to the last. Thanks to this, his son, Vyacheslav – then just a child – was saved.
Then, Svetlana, Pavel's sister, who had once left her homeland to study necromancy in the Seven Cities and became an outstanding necromancer, was called home. She took the place of regent for Vyacheslav and took on his education in accordance with the traditions of the Griffon family.
Fifteen years passed, and the war became a thing of the past. Duke Vyacheslav became the father of five promising children. They are the heroes of the Heroes VI campaign, and they will lead the inhabitants of Ashan into battle.
* Nowadays, the calendar in Ashan is counted from the day when the legendary prophet Sar-Ilám achieved enlightenment and was deified as the Seventh Dragon. Little is known about the events that preceded this, but judging by the ruins of ancient civilizations, Ashan has existed for thousands of years.
