Nocturion is a medieval world that resembles our own - with a darker twist. You, as an inhabitant of Nocturion, will build strongholds and populate them with buildings and armies to defend themselves as you grow your influence over the world.
But of course, you are not alone.
You will encounter necromancers and their armies, conclaves of ghosts, vampire lairs, haunted towers, undead wizards and, well, dragons. Some of these beings may be hostile, while others can be subjugated into serving as a supernatural army.
And this is just the beginning.
Surrounding Nocturion are the Elemental Planes. The rulers of these planes are hostile, raging war with one another, which is why they are leaving Nocturion alone... for now.
