The Planner Scenario is a collective term for the universal structure of Ludo-Rathowm's world, created by Supreme God Planner, who is constantly making sure that a balance is preserved within the scenario.
The elements that make up the Planner Scenario are:
The Human Territory is the area on the eastern side of the Continent, first established during the reign of Demon King Gi. Many internal conflicts amongst humanity brought about the rise of the four main territories within the overall human territory.
The Helman Empire dominates much of the north and north-west sections, the Kingdom of Leazas has claimed the fertile soil to the north-east, the Magic Kingdom of Zeth owns the land to the south-west, and the south-eastern section is made up of an alliance of Free Cities. Additionally, there is a floating landmass known as JAPAN to the east of the mainland.
Between Zeth and Helman and east to the Crystal Forest, there's a huge desert called the Kinani Desert. This desert is a death-zone for humans since trying to pass is suicide with the sand-storms and the huge path of sand. This made it impossible for Helman or Zeth to try to invade the other. There's one small nation called Shangri-La in the middle that is completely independent of everything else.
The Kalar Race reside in the Crystal Forest in the centre of the continent and are unified under a single country called Pencilcow, founded by Index Kalar and Hanty Kalar. Humans are not allowed to enter and are either killed on sight or captured for breeding purposes until they die.
The world is currently divided into these major powers, and humanity is rarely in unison. Though there have been attempts to unify humanity, such as Emperor Ishimaru Fujiwara's conquest during Demon King Nighcisa's reign, there has only ever been one successful unification of mankind in history and that was during the reign of the Holy Magic Sect. That time, however, has long since passed.
Ever since Ishimaru Fujiwara conquered most of the continent during Nighcisa's era, JAPANese became the prominent language in the world and it remained that way until the present. The old language has long since been lost, though there is a handful of extremely old individuals, such as Dark Lord Galtia, that are knowledgeable of it.
Leazas ≈ 50,000,000 people
Free Cities Alliance ≈ 48,000,000 people
Helman ≈ 51,000,000 people
Zeth ≈ 32,000,000 people
JAPAN ≈ 20,000,000 people
Shangri-La ≈ Unknown
Pencilcow ≈ 2017 Kalar.
The Sea ≈ 0 people
Independent ≈ 87,000,000 people
Total ≈ 300,000,000 people
Independently of the nations, large organizations with a great impact on the world exist or have existed in the past.
The Monster Territory is the area on the western side of the Continent, first established during the reign of Demon King Gi.
Prior to Gi's rule, Demon King Gele had monsters swarming all over the Continent as she cared little for humanity or any living comforts they might feel entitled to. Gi changed that by allocating territory for monsters and territory for humans, the monsters were mostly called back to the western half of the Continent and formed the Monster Realm, while the humans were left to their own devices on the eastern half.
During the division of the world dictated by Gi, a majority of the antagonist race was put together on the west. Monsters continued to exist within the human territory, just in smaller numbers than they do in the Monster Realm. Higher numbers of them are more commonly seen within the area where Zeth and Helman both border the enemy territory, but that was fixed by erecting superstructures to act as physical barriers and defensive lines to protect humanity from the Monster Realm. Zeth constructed the Maginot Line, a complex and high-tech magical defence system, while Helman constructed the Fort Banra, an enormous stone wall that soldiers can live inside. These two structures make up a visible line between the territories of man and monster.
Most of the monsters live here, along with Dark Lords, Apostles and the Demon King. Beyond the Monster Forest, which marks the boundary between the Monster Realm and the human kingdoms. The Realm is a huge greyish landscape with a very obscure and dark atmosphere. It is foggy and full of thick clouds with constantly heavy air, humid, and it feels like you're breathing miasma. The monsters like it, but to a human, it would feel like fatigue was constantly eating away at them.
Death is almost guaranteed for humans that enter to the monster realm, not only because of the hostile landscape and the overwhelming amount of monsters that inhabit it, but because it's where Dark Lords live, and an encounter with one would be near-certain death for any human.
