I loathe and despise all humans. I would be more than happy to see all humans die horrible deaths (excepting myself, of course) - so long as I could still somehow acquire food and the accoutrements of civilization. But enough about real life, this forum is about D&D.
I must admit that my campaign is very humanocentric. Elves do exist, off in a tiny corner of the continent, but their once-great empire fell centuries ago and the race has been on the decline ever since. Gnomes and halflings are around, but I don't believe the characters have ever encountered any. And they've only heard rumors about the dwarves, though that last may change soon.
