Okay, cool. I'll go ahead and drop the dwarf lore you need here so you don't have to go hunting for it. Dwarves live in small clans in a large mountain range about 1000 miles north of where the campaign is taking place. Some of them live north of humans, some of them live north of elves, and some of them live north of the druid-run nation of Fianna. That will determine who their allies are. Dwarves and giants are in consistent conflict, as giants used to live everywhere but have been driven north over time. Clans don't normally team up for any extended period of time, but something extraordinary happened just recently in the setting.
Just over a year ago, Kerg Balan, of the powerful Balan clan, allied himself with Fianna and was elected Warleader, a position that only lasts for a year and allows him to command other dwarf clans in battle. Some of the dwarven clans who live far to the west among the elves couldn't make it to the vote in time and were very resentful of him. So there are basically two factions of dwarven clans - ones that were happy under Clan Balan's banner, and those that were not. That will determine how you get along with other dwarves and will change your options slightly for what you spent the last year doing.
