Brahn is a half-orc master blacksmith, previously travelling with the infamous merchant Rahm. Together, they ran a reasonably successful business, with Rahm doing the talking, and Brahn doing the work.
This agreement was especially helpful for Brahn, as he is mute, and struggles to communicate with people in order to sell his wares. And besides, he struggles to understand and get along with most people anyway, let alone to try to make a sale.
He is now travelling alone, after Rahm's demise during a pirate attack on an Ellonde waycastle along the Golden Coast.
