Honestly, the Brewer you describe sounds like a member of the Teamsters union under mafia rule. I don't see why a Dwarven guild of brewers might not eventually rise to a political position, which might then see corruption from the mafia. You're a "Brewer," except you're actually an organized criminal whose benefit of Position of Privilege is entirely due to overwhelming corruption and the threat of reprisal.In case you failed to notice, none of the mechanical abilities are representative of what the background is actually supposed to be. A brewer should be good at brewing, because that's what those words mean. This "brewer" has, not only a complete inability to brew anything, but influence within high society as a result of their noble birth. (Which they don't actually have, because they weren't actually born noble. But people are still inclined to think well of them, because of their noble birth, as a brewer.)
It's a direct violation of the central premise behind any role-playing system: that the rules of the game reflect the reality of the game world. None of these abilities reflect anything about what it means to be a brewer.
