@Rin:
First page of the Hermit background, only missing the Bond and Flaws table; all of those tables are merely suggestions if you have no other ideas how to proceed. I can get an image of the second page though if you'd like.
As for the Urchin, they get the following:
Skill proficiencies: sleight of hand, stealth
Tool proficiencies: Disguise kit, thieve's tools
Equipment (not applicable, but might help fill out your gear): A small knife, a map of the city you grew up in, a pet mouse, a token to remember your parents by, a set of common clothes, and a belt pouch containing 10 gp.
Feature: City Secrets - You know the secret patterns and flow to cities and can find passages through the urban sprawl that others would miss. When you are not in combat, you (and companions you lead) can travel between any two locations in the city twice as fast as your speed would normally allow.
Urchins grew up on the street, struggling for food, shelter, and enough money to live by. Basically, you're Oliver Twist or the Artful Dodger (though he may have a bit more of Criminal in his background).
To everyone: Backgrounds can be customized and shifted around as well, so if just about everything works but one part, you can swap something in or out, or you can make up your own background, selecting any two skills (these should be applicable to your background), up to two tool proficiencies or languages (can mix and match), and a Feature, either one from any of the listed backgrounds or we can work to come up with something appropriate to your history.
@Gazzien: Looking good so far. Just as a reminder, your list of prepared spells is a single pool (in this case, your Int mod + your wizard level = 7), and you can prepare any spells of any level you know in that pool up to the limit, rather than having a separate pool for each spell level.
@bhu: Sounds good! Seems like he could easily have a bit of both Sailor and Outlander backgrounds, so you could mix and match the proficiencies of both into one background if you like. I'll try to include some particularly nasty Orcs for Liver-Eating Johnston to disembowel.
@linklord: Excellent! That's perfect, and gives me plenty of material to work with to
torment integrate your character into the campaign.
