Race War isn't cool, guys.
First ever tabletop game for everyone in the party, including the GM. I decide to be a Half-Elf Warlock (D&D 4th ed).
We end up in a magic-denying human kingdom. They believe all magic is something only elves can produce, and that it’s to be distrusted, if not feared.
So the party is walking through the streets at midnight (I’ve been hiding in my hooded cloak, elf ears and all that) and I get a Perception check to notice my pocket being picked by someone who’s been sneaking up behind us. Being a Chaotic Neutral kind of fellow, I cast fire spells first, ask questions later.
It was a street urchin.
Evidently, the guards found the charred body, and the king of the land declared war on his elvish neighbors, blaming all elves for this heinous crime that could only have been committed by magic.
So that’s how I started a Race War. How I ended a Race War is a different topic altogether.
