Arvalon

Arvalon is the setting of the events of the World of Dreams & Nightmares series. Primarily, the titles in the series are set on the fictional continent of Mytalia, which is split into seven major regions (Jorland, Castalia, Yan Song, H'Radda, The Green, Drakkis Isles, & The Orange Archipelago). Mytalia is also connected to a much larger, snow-covered continent called The Uncharted and it is separated from all other landmasses by both the Lower Sea and the famous and massive Great Sea.

Mytalia was once the home of humans, elves, and dwarves, ala J.R.R. Tolkein's Middle-Earth, but the latter two were wiped out, which caused new races to rise up in their place. All of Mytalia is under the rule of the King of Kings Malael Drakkis, who conquered it hundreds of years ago and is responsible for the genocide of the dwarves and elves.

Mankind
The only surviving race from during the Pre-War era. "Mankind" and "Men" are the term used to refer to humans in the Dreams & Nightmares world and, unlike most other fantasy stories, they are rare compared to other races. There are only around 1,000 known humans across the entire continent of Mytalia and they mainly live in small villages, though they are sometimes also seen in large cities but in small numbers. In the Arvalon world, Mankind are the direct descendants of the mysterious Vants, who hailed from a far-off land and have since gone missing.

Golems
Stone humanoids built by the dwarves before they were killed. After The Final War, they took over their creator's cities and have developed sapience over the years. They all have grey rock skin and have gemstones growing out of their bodies. Their gemstones will always be one of the five cardinal gems (diamond, emerald, ruby, sapphire, amethyst) and the gemstone growing out of them determines their expected role in society. Diamond means the Golem is expected to be a leader, emerald an advisor, amethyst a general, ruby a soldier, and sapphire a wizard, although there are several exceptions to this. Golems are also genderless and generally have level-headed and rational to a fault personalities, though some Golems are considered "gendered", which involves them carving their own bodies to resemble a male or female and taking on more emotional personalities.

Makaka
Makaka are a race of monkey and ape-like creatures descended from actual monkeys and apes. During the events of The Final War, a magical fountain's guardian was killed and some local simians drank from it, gaining human-like intelligence and the ability to speak in the process. Over the years, they have become more and more humanoid in their appearance, able to walk up-right and growing much taller. The fountain they drank from has since become a major part of their culture and is located in the middle of the Three Golden Cities, which are located in Yan Song and by Makaka. They are infamously xenophobic, unwilling to trust non-Makaka and treating outsiders with suspicion and hostility. They are heavily inspired by Chinese culture, a reference to Sun Wukong, and the plural of Makaka is Makaka.
