I have some new creations ready for Heroes IV WoW.
First is a 6-map rpg campaign called the Sorcerer King.

Take a long journey through generations of a bloodline and through the realms and countries of the world.
Reconquer the lands that was taken from your ancestors and revenge your family.

My other map, Forgotten Realms, is made as a singleplayer map, but should work well as a multiplayer as well (a MP version is included in the zip file). The map includes the summary 101 reasons the archmage isn't home.

You see more screenshots from the Sorcerer King at this page.
