This is a note for the naming of the beasts and monsters, plus a little bit of information regarding the world.
0th Stage of Evolution: Usually race name only (Slime, Wolf, etc.);
1st Stage of Evolution: Adds a modifier before the race name (Big Slime, Big Wolf, Angry Boar, etc.);
2nd Stage of Evolution: Adds the element, specialty, or special characteristic of the monster before the race name (Shadow Wolf, Ice Fairy, Orange Phoenix, etc.);
3rd Stage of Evolution: Usually adds a modifier before their race name plus another modifier depending on the potential of the monster (Royal Slime Princess, Shadow Werewolf Assassin, etc.);
4th Stage of Evolution: Entry to Peerage Acquisition; usually adds a Baron to their name, which is determined by their specialization (Baroness of Infinite Changes, Baroness of Shadowless Death, etc.);
5th Stage of Evolution: Upgrades from Baron to Viscount; usually keeps the part after the Baron intact (Viscountess of Infinite Changes, Viscountess of Shadowless Death, etc.);
6th Stage of Evolution: Upgrades from Viscount to Count; usually keeps the part after the Viscount intact (Countess of Infinite Changes, Countess of Shadowless Death);
7th Stage of Evolution: Upgrades from Count to Marquis; usually keeps the part after the Count intact (Marchioness of Infinite Changes, Marchioness of Shadowless Death, etc.);
8th Stage of Evolution: Upgrades from Marquis to Duke; usually keeps the part after the Marquis intact (Duchess of Infinite Changes, Duchess of Shadowless Death, etc.);
9th Stage of Evolution: The last stage of transformation, earning them the title of King or Queen (the only exception to exist yet is the Judge of the Impartial Heavens). It adds a territory under their name, depicting that the monster's skill is the best within that territory. The wider the presumed territory, the stronger the power. For example, the King of Hell's Bastion is weaker than the Queen of Heavenly Ice Palace, as a bastion is definitely smaller compared to a palace. If the territory reaches the size of a country, like the Queen of Death's Phantom Kingdom, then it expresses the potential of the monster to reach God level.
God Evolution: God Level expresses the notion that the monster had reached the peak of its specialization. For example, Zeta is considered the Goddess of Space. If another monster wants to become the God of Space, then they would need to possess stronger abilities than Zeta regarding that specialization. But the quickest way would be to eliminate the one in the God position to make the said title vacant.
As of the current date, only five tamers possess god-level monsters. Zeshion had 10 of them at God-level, each with their own specialization. The other four god-tamers have around 26 god-level tamed monsters combined, adding up to a total of 36 claimed specializations. Adding to the past records, there should be about 100 God titles discovered, but nobody has reached the peak of the said specializations yet, claiming a God's seat.
???: The unknown stage that was theorized to be above God's level; The Judge of Impartial Heavens, possessing a unique modifier of "Judge" and the territory span of the "Heavens," was suspected to be able to reach this stage, but nobody knows if it really could.
