From the author: The campaign is a direct continuation of the "Warrior" campaign. The story will tell what happened after the destruction of the demonic citadel Ur-Veshaal. This is an Inferno faction campaign. The entire plot is the author's fantasy and does not claim to be canon. It is also not recommended to play this campaign on global modifications (such as EWA and Heroes 5.5). Have a good game!
