Tian Bo is a compact, broad dwarf with a square, soot-browned face and burn-scarred forearms that shine taut and reddish when the forge is hot. His beard is braided into three blunt cords, each tied with a different bit of copper wire, and his hair is cropped close around a scalp marked by fine pale flecks of old ash. He stands with his weight tipped toward the balls of his feet, as if ready to turn toward whoever has just entered. His work shirt has been patched at the elbows with mismatched blue cloth, while his little amber pin is polished so carefully it catches the eye before his battered apron does. Unexpectedly, he keeps a tiny, painstakingly tended pot of white clover on the smithy windowsill and stops to turn it toward the morning light.

Tian Bo is generous with his time and loves a good story, yet he rarely lets a conversation go where it wants without nudging it toward something useful. In easy company he is expansive, teasing, and quick to offer help. When frightened, he becomes brisk and practical; when someone threatens his neighbors, his friendly manner gives way to a hard, unsentimental focus.

Tian Bo was apprenticed to a smith who repaired the Ember Quarter's stoves, hinges, and ironwork. He learned its history the practical way: by listening to neighbors argue over whose family had built which wall, then checking their claims against old maker's marks. Years ago, a furnace collapse trapped his mentor and several tenants in a service tunnel. Tian Bo used a forbidden cantrip to draw smoke away from the trapped people, but the effort and the heat blistered both his forearms. His mentor survived long enough to tell him that the Quarter's founding records were deliberately incomplete. Since then, Tian Bo has split his days between smithing and piecing together the district's past. His closest confidante is Yelun, a retired lamplighter who remembers the old altar's renovations; his former apprentice, Oru, now works for a property factor pressing to clear the old shrine. Tian Bo is trying to keep the shrine intact while quietly investigating signs of fresh digging beneath it.
