Okay, if everyone who has posted here is definitely going to play, then recruitment is closed for the Heroes of Fannen-Dar. Here are our players:
Shayuri: Human wizard (controller)
Walking Dad: Dwarf warlock (striker)
The Digger: Dwarf paladin or fighter (defender)
EvolutionKB: (Unknown race) bard (leader)
Bihlbo: Halfling rogue (striker)
Pyrex: Warforged fighter (defender)
If these are everybody's characters, then post them here when you create them! Digger, since Pyrex is being a fighter, I suggest being a paladin (for variety's sake), but it's up to you. Two fighters could be quite useful! The campaign was created for 5 players, so I'll just up the XP in every encounter and it will even out. Rooms may have to be made bigger as well...
As for backgrounds, I will now post different ideas for backgrounds here (based on your proposed race and class).
Shayuri: Humans, of course, come from all over. Wizards (in this world) tend to be of more noble blood (since they have access to more tomes of arcane knowledge to study from). There are a few rich families in Fannen-Dar, but a much larger city lies to the north of the small town, and it is called Rayshin.
Walking Dad: Morgran, as you said, worked in mines, so the best place for that is of course the city Gortul, to the east of Fannen-Dar, built into the sides of a cliff by dwarves, still ruled by the dwarven royalty, and also home to several underdark dwellers. And of course, there are several tunnels, some going extremely deep into the mountains.
Digger: As I said for Walking Dad, lots of dwarves come from Gortul, but many also reside in Fannen-Dar. You can too come from Rayshin, but not only are dwarves there scarce, so are fighters. Paladins, though, abound in Rayshin, from the many religious temples there.
EvolutionKB: Bards come from many places, but depending on your race, you may choose a different origin. Fannen-Dar is of course home to many bards, mostly elves, half-elves, eladrin, dragonborn, dwarves, and humans, but other races as well. Eladrin come from the shining city of Regalia, hidden in the Cloak Woods but known to many. Rayshin is home to all sorts of races, and many bards earn a living in its streets. Gortul isn't a very popular place for music and poetry, but it does exist there. A small town to the west of Fannen-Dar, Hillside, is home to many nature-loving races, and a lot of bards. Even beyond Hillside is Seaside, which is of course next to the sea. Halflings and ocean-loving races come from there. It's up to you what your race is.
Bihlbo: Halflings, being naturally nomadic, can come from very many different places, including Fannen-Dar, Hillside, Seaside, Rayshin, and the far-off marsh-town of Rarsh, which is inhabited almost exclusively by halflings. Rogues, of course, come from all these places, mostly as street urchins, but sometimes as tricky nobility (though Hillside, Seaside, and especially Rarsh are not places with much nobility).
Pyrex: Fighters tend to come from more rural areas, but warforged are built in cities with access to the required rituals for making them, and then trained as fighters to be in the army. Rayshin and Regailia are possible examples, but the military Gortul is also a possibility. The likelyhood of a warforged coming from Fannen-Dar is small, it's next to none in Hillside and Seaside, and definitely not from Rarsh.
To all of you, you can ask as many questions as you want. If you have not lived in Fannen-Dar for your life, you need a reason for being there now, whatever that reason may be (as long as it is not leaving your town because it was destroyed, because the nearby towns and cities have not been destroyed). If you want, you can come from a far away land, but you need a reason for traveling that far. The reason I want details of your character background is that when you return to a city or town where you once came from, you can know things about it and gain an advantage at, for example, finding shops that sell items cheap, or have contacts in those cities. I may take the liberty to adding to your background as the story progresses (you may meet an NPC who knows you and who you know).
Okay, I can't wait to see these characters! The game will be in the Play the Game forum, and won't start until after the Player's Handbook 2 has come out (unless everybody objects), so check there March 18!
