Today I just want to elaborate on the different versions of character that (almost) the same story can make, in particular, Mountain's Son.
We left him as a dwarf, with the unique of having been born from a geode. I think he has 3 points in a positive relationship with the Dwarf King; as for backgrounds, he's Miner in the north mountains 4 since it's been most of his life, and then Dwarven traveler 2 and Legend seeker 2, because of the travels he's made searching clues about the meaning of his birth.
And the class is the point of that post I mentioned before. The Dwarven armored Fighter is the first image of a lot of people. He would dress in heavy armor, carries a shield and a war-pick. Maybe his helmet is made from the geode he was born from. He definitely has the Tough as Iron and Heavy Warrior talents. Defensive Fighting is a combat maneuver that makes him even harder to hurt and Carve an Opening brings me images of hacking at a foe as he picked at the mine.
Now let's make him a more primal warrior. He has not any training, after all, just natural toughness, mulishness and muscles made from mine work. Now he's a Barbarian. His gear is the same but for the armor, now lighter, maybe the hides he used to protect from cold weather or burning from melting ore. As Barbarian, two talents are clearly Unstoppable and Strongheart, letting him shrug off his foes' hits. I would probably give him the Cleave talent too, mostly because of the adventurer feat to let him heal (again), although at first level I would probably select the Unstoppable feat.
If that's not primal enough, we can make him a druid, most probably Terrain Caster adept since he has such a strong connection with earth in general and mountains in particular.
A final option, maybe more surprising to other characters and players, would be to make him into a Bard. He should have the Mythkenner talent to let him use Wisdom instead of Charisma and raise his Legend Seeker background to 4. Since he's legend seeker and not song seeker, I would take the Storyteller talent too, and probably the Battle Skald talent, to not forget dwarves are famous warriors.
Now, he does not use a shield and probably he sings without instruments, with his low, rumbling, dwarven voice. In this case, though the typical bard we have in mind is more a rapier or sword swashbuckler, I would want him to use the pick he used when mining, to not forget where he came from.
