I had this alternate world idea where elves were Fey, not humanoids.
Not only that, but they could nto bear the touch of metal, they used Witch Wood (darkwood), or leather/hide for thier armor.
They could only be Druids, Rangers, Sorcerers, Bards, or Rogues - they did not worship god, but revered nature
And Dwarves would be literally born of the earth (outsider, earth)
They were the one's who introduced Iron to the surface dwellers, keeping Adamantine for themselves. They could only be Fighters, Clerics, Rogues, Transmutation, Evocation, or Conjuration Wizards. They are barred from Enchantment, and Illusion schools.
Still working on gnomes, halflings, and 1/2 orcs....
Although I have a feeling that 1/2 orcs would make up a larger population of the planet than humans. With a high sex drive, and a tendency towards mutiple births. And Gnomes invented mithiril, of that I am sure. Isee halflings as either a Xenophobic tree/jungle people (bracination, anyone?), or a very fearful race. Thier tiny stature and lack of strength in a violent work would make them naturally reticient to socialize.
Anyone want to help me flesh this out?
