My group is not one to plan ahead very far; we are starting our game in less than a week, and none of them have backstories, only one has a name, several haven't completely settled on a character, and one has yet to even read the Player's Guide. The group, which will likely only be finalized the night the game begins (if I'm lucky), so far looks something like this...
LG human (Chelaxian) fighter
NG human (Varisian) cleric of Desna
NG kobold druid
Levanter, CG air genasi (Chelaxian) swashbuckler
CG human (Varisian) bard
CG litorian swordsage
CN human (Varisian) cleric of Calistria
...However, knowing them, I fully expect them to change their minds and morph into a herd of yakfolk necromancers and warlocks five minutes before the first session.
