Um, I would just like to say that the language of magic is a poor common language, and one which should not be spoken casually. It's a good way to shoot your eye out.
And for the record, I use tons of segregation in my D&D Games.
Oh, and I increased the human lifespan. I can't stand the idea that Elves and Dwarves live 10 times longer than humans. How could they possibly contain similar mental stats if they had to live three lifetimes just to reach adolescence. I generally pull that comparison up to 2:1, or I make other races unplayable.
Also, I really do love dwarves and elves. They are just great races. I'm glad to have them.
