I never promised that Elemental would be a simple game. I just promised it would be good. 
For casual players, there are factions. Elemental has 10 default factions or you can create your own.
Next up are Allegiances. This is also of interest to casual players. The Kingdoms and the Empires. Pretty straight forward.
Now we get into the more hard core stuff. For people who are into this stuff like we are. You have the races and the classifications.
First, let’s start with classifications. There are Men and there are Fallen. Men are sentient humanoid beings that are “natural”. Fallen are beings that were created by the Titans. The Sentient Fallen were created using Dragons and Men in parts – sometimes mixed in with other stuff.
When Master of Magic was developed, such talk of “Fallen” would probably have seemed totally the realm of “magic”. Today, however, we can imagine a day where scientists begin using DNA from various animals to make “better” humans. That’s basically what the Fallen are as a classification.
In Elemental, the world of “Men” is a broad classification. The Ironeers are men but in another universe they might be called dwarves. But Ironeers in Elemental are men.
There are 5 races of “Men” and 5 races of “Fallen”. Each is quite different from one another.
I’m a Tolkien fanatic so let me put it in Tolkien terms.
The Kingdoms would include Men, Elves, Dwarves. The Empires would include Orcs, Saruman version Orcs, and the Easterlings.
Of course, in Elemental, players can toss all this out and make their own race if they want. I made a Na’vi today in our internal build. I decided to make them aligned with the Kingdom. Are they “Fallen”? You decide.
