Ok, here's a pretty lame one. I arranged a D&D meeting once with the intention to finish up all the half-baked characters produced in the last meeting. Only one guy showed up, and after we finished his character, we decided to make the best of the time and talk about a backstory. His character was a half-gold dragon elf barbarian named Quarion Gix Holimion (he added "gix" to his name later, it's Draconic for "claw" or something), and he grew up in an elven community at the base of a mountain range where some gold dragons live. Apparently, he's the illegitimate son of a bored adolescent gold dragon and an elven barmaid. When he was born half-dragon, everyone in the village wanted him to get the best education of elven traditions like swordplay, archery, and magic that their dirt farming town could provide. However, it would be difficult to raise him as a stereotypical haughty elf if he was only half elf and and illegitimate one at that, so they hid this fact from him while he grudgingly studied. However, when he was 20-something (the adult age of elves in my campaign), his mother told him that he did not, in fact, have a rare skin condition- We had to take a break, we were too busy laughing. Anyway, he runs away, joins a nomadic tribe of lupins (those wolf dudes from Dragon Compendium), gets his barbarian training, brefriends a lupin ranger who is another PC, and they set off to explore the world, when they eventually meet the rest of the party.
