When you say we need to build up our guild, do you mean we're founding an adventurer's guild, or are we trying to increase the reputation of our party so the guild improves its standing by having us?

Are the secondary skills are like specializations or focuses? Are we starting out as masters in our craft?

Do you want to touch on personality?

In your OP, you mentioned the races are a little divided. So does this city they're in have like a dwarven quarter, a human quarter, etc? Or is there a dwarven underground kingdom and an elvish kingdom in the forest next to the city?

Are you just accepting the standard races of Human, Elf, Dwarf, and halfling? Are there half-elves in this world?
