Gates of Hell

Map description and plot:
Our hero is half-demon/half-angel. His military talents and skills have leaned towards evil, while his magic has leaned towards good. During the demon invasion, which emerges from the opened Gates of Hell, he realizes that humans cannot cope and decides to enlist the support of a lord to close the gates. However, upon arrival, he learns that the lord has disappeared under mysterious circumstances, and his kingdom has been destroyed. In this map, we must find out what happened to him.
The map is made in the form of a campaign to add an intro, as well as a subsequent continuation. Have a nice game, everyone! I hope you enjoy it! Write your ideas and suggestions in the comments!
