Royal Rule:

In this kingdom, all royal children must demonstrate the ability to use magic by the age of 15. Failure to do so results in exile or execution, ensuring only those with magical prowess maintain the royal bloodline's integrity.

1. Olethros, The Disaster

Known for causing widespread destruction wherever they appear.

2. Mahlon, The Weakness

A cunning demon who exploits the vulnerabilities of others to devastating effect.

Other Warlords exist, but their names and powers remain unknown, shrouded in mystery.

Monster Ranks:

Monsters are classified based on their rarity and danger level:

S-Tier Monsters

Rarely seen, dragons are harbingers of calamity. Their arrival signals disaster on a massive scale.

2. Phoenix

Demonic Monsters

Demonic monsters are creatures born from the influence of hellish energies, more dangerous than their natural counterparts:

1. Rabbit of Hell

Appearing harmless, this demonized rabbit is incredibly deceptive. Its agility, razor-sharp teeth, and ability to summon flames make it a deadly predator.

2. Hellhound

A fiery wolf-like creature, often used as a guardian by demons. Known for its relentless pursuit of prey.

3. Nightmare Stag

A ghostly deer with glowing antlers that can manipulate shadows to disorient and ambush its enemies.

4. Infernal Unicorn

A corrupted version of the unicorn, its once-pure magic is now dark and destructive. Infernal unicorns use shadow flames and curses to devastate their opponents, making them one of the most feared demonic creatures.
