Human Civilization is one of the participants in the Battle of Divine Will. They can be found in Divine Land's 4 picture scrolls, their representative seems to be constantly changing over the course of history. Their current location is in the southeast of the continent, behind the Impassable Mountains, and Fjord islands in the Vortex sea.
Human Civilization is divided in several societies:
During the first Battle of Divine Will, witches and common people were collaborating to fight against demons, but the core of the fighting forces were witches with their abilities.
The Witch Federation was founded after the First Battle of Divine Will by the survivors, the Union had transformed from an unofficial alliance to a unified political entity.
Humans were led by witches alone, common people didn't held political power.
After the First Battle of Divine Will they were reached out by the Underground Civilization, and began to slowly discover their technology.
The survivors fled to the Barbarian lands, and established themselves, creating the 4 kingdoms, fjords merchants, and the Church.
With the Witch hunt and the secrets of the Church, the humans lost their knowledge of demons, and witches regressed in their use of magic.
During the Third Battle of Divine Will, groups such as the Taquila Witches, Sleeping Spell, Witch Union, and the Kingdom of Graycastle are united to fight against demons, with Roland Wimbledon as their leader.
They are now fighting against demons in the north with the Kingdom of Wolfheart as battle line.
