In the beginning-

Wait, no,

After the Beginning, two swords were made by the gods: Gods' Horn, and Guillotine.

The scene changes from darkness to illuminated, twin swords, one crackling with red lightning, the other surrounded with a soft red glow, the background changes from black to white fading to grey.

These blades were made by two gods, twins, Hephaestus, and some other Elder.

Gods' horn was made as a gift, while Guillotine, was a plot, to switch the twin blades around so that it killed the user.

Hephaestus lost his twin and was imprisoned by several other Elders-

AH! I'm sorry, I should explain what exactly the races are, as you're gonna be in Archen soon!

The Elders, or Gods, are few and far between in the real world, although the various bordering Shadowrealms contain many Eldari. The Eldari never wander too far from home(you cannot use them as your character race)

Elves are similar to Elders, though the two races are distinct, though a half-blood with both sides would be nigh unkillable... Elves are proficient in many forms of magic.
Dwarves are a strong, religious people, they work with metal like no others but the Eternal Forger, but anyway, I have seen the Dwarves work impossible metals and sculpt things that defy the laws of the universe, they are also fiercely loyal to their clan and family members.
Humani (or Humans) have brought the most change to this world, and many of the Elders are not happy. I, for one, am content to sit and write. You probably know mostly Humani lore, but they make up for lack of specific skill with adaptability and creativity that surpasses even an Elf-Elder Half-Blood.
Half-Bloods are many things, always a taboo thing, and shunned by most, they, however, can only be made by an Elder procreating with a member of another race, an Elf-Eldari is the rarest and most powerful Half-Blood.

And now, the artificials
Golems are artificial beings who are animated with an unbreakable spell, they can be made with literally anything.
Tulpa are beings of material, like golems, but different in that they are not actually with mind, but are mindless.
Dollic Races: most of these races are made through spells on one person and that person spreading their genes onto humani and creating more of that race.
