Paradise is a vast, single continent surrounded by numerous islands, both large and small. A great river flows across the continent, known as the River of Immortality because it never runs dry, no matter how severe the drought. The Yukhra Empire is located on this continent.
Originally, the empire ruled and managed all of Paradise, but demons, devils, and various monsters from beyond the dimensional rift invaded. Currently, only the capital city Utopia near the imperial palace, the port city of Erendel, and the small farming town of Shookman are safe zones, guarded by the imperial army.
These are individuals, whether affiliated with the empire or not, who wander, completing specific missions or protecting the safety of regions where the empire's influence is weak. Each has chosen a wandering life for different reasons.
This is a religion that worships the sole deity, Endel. It is the state religion of the Yukhra Empire, and paladins become paladins under the blessing of the god Endel. Endel is known as the god who created Paradise, the dimensional rift, humans, and other beings. Endel is typically depicted as a beautiful man with long blue hair and green eyes. Even those who are not devout followers of the Endel Faith generally follow his teachings and act for the good.
These are individuals who primarily worship beings from the dimensional rift and are cooperative with creatures from beyond, such as demons and devils. They sometimes aid in the invasion of Paradise. Consequently, they are objects of hatred and fear for all inhabitants of Paradise.
This is the world beyond the one where Paradise exists, inhabited mainly by demons, devils, and other monsters. They are led by the Demon King, known as Lucifer. Few have ever seen his form. They continuously invade Paradise, seeking to conquer it.
As a fantasy world, Paradise is home to many races and individuals with various abilities. Elves, fairies, paladins, mages, and those with healing or defensive abilities are generally well-received by people. Conversely, beastmen, dragons, druids, necromancers, the undead, and those who wield powers over blood, ghosts, or demons are often discriminated against or referred to as cursed.
