Heroes Chronicles is a series of spinoff titles based on the Heroes of Might and Magic III game engine, including Heroes III scenarios. The scenarios were the only playable parts included; for features such as single maps, a map editor, or multiplayer, buying the original Heroes III was still required.
The plot of the Chronicles was set on Antagarich, tied together by the character of Tarnum, who leads various armies and factions throughout them. The released Chronicles were:
Warlords of the Wasteland (2000). Tarnum's original story, as a young Barbarian leading an uprising against the oppressive Wizard-Kings of Bracaduun.
Conquest of the Underworld (2000). Tarnum's first adventure as the Immortal Hero as he adopts the guise of an Erathian Knight in a campaign against the Demons, Necromancers and Warlocks of the Underworld.
Masters of the Elements (2000). Tarnum becomes that which he hates most, a Wizard, in a hectic bid to assist the Wizards of Bracada in their quest to save the planet from the destructive Elemental Lords.
Clash of the Dragons (2000). Tarnum takes up the bow and defends the Elves and Dwarves of AvLee as a Ranger while opposing the tyrannical Queen of Nighon, Mutare, and her legions of murderous Dragons.
The World Tree (2000). As a Barbarian, Tarnum defends the World Tree in northeastern Antagarich from evil Barbarians and Necromancers led by the demigod Vorr. This was available as a free download for those who purchased two Heroes Chronicles games, but the installer could only recognize the North American version.
The Fiery Moon (2000). The sequel to The World Tree continues Tarnum's quest as, in hot pursuit of Vorr, he travels to a moon populated by the demonic Kreegan. This was available as a free download for those who purchased three Heroes Chronicles games, but the installer could only recognize the North American version.
Revolt of the Beastmasters (2001). Tarnum travels to the Mudlands of Tatalia, becoming a Beastmaster to free the Mudlanders from the oppression he brought upon them centuries ago. This campaign was one of two included in the single-disc installment, The Final Chapters.
The Sword of Frost (2001). Tarnum must become a Dungeon Overlord of Nighon to stop his former friend, the Elven Hero Gelu, from discovering the Sword of Frost. This campaign was one of two included in the single-disc installment, The Final Chapters.
