In the Human Domain, where humans are able to seek sanctuary from the beast race, they began to flourish once more. But despite being called the Human Domain, its lands were not been fully conquered by humans.
There were four regions in the Human Domain that could not be conquered by humans since the time of its formation. Such places were referred to as the Perilous Land, a natural death zone to all who tread its territory, except the strong and abled. In spite of the dangers that exist within the Perilous Lands, it doesn't stop people from braving it for the fortunes and secrets that lies within.
