The Story of Braum
Braum grew up in the Freljord's harshest territory and came to the attention of legend through an act so straightforward it has the quality of myth: he spent an entire night and day punching through a solid vault door with his bare hands in order to save the children trapped inside. He brought them food when the door finally gave. He didn't explain what he'd done. He was already thinking about what needed to happen next.
He carries an enchanted shield made from a piece of that same vault door — the stone he punched through, given a form that made it useful. It is enormous. It stops nearly everything. Braum himself stops everything else. He moves through the Freljord offering his protection to anyone who needs it with the particular generosity of someone who has enough to give and no reason to keep score. He is not performing kindness. He just genuinely doesn't see the point of having strength you don't use to help people.
His legend in the Freljord is something between folk hero and tall tale, which is appropriate because the man himself is something between impossibly capable and entirely sincere. Children in the Freljord grow up on Braum stories. Adults who meet him discover that the stories underestimate him in the directions that matter most: he is more patient, more generous, and more genuinely pleased to see people than any legend quite captures. The mustache is exactly as advertised.
