Locals say the tavern sits upon a keystone called the 'First Wedge'—a carved stone said to bind the neighborhood's foundations with old dwarven runes. The Stoneheart Amber is brewed from a yeast strain supposedly cultured from a vat salvaged during the Great Quake; some believe it strengthens the bearer’s resolve. Rumors tell of a hidden stair under the fourth cellar barrel that leads to storerooms of the old clan house, sealed with a ward keyed to a Stonehelm blood-sigil. Duergar interest in the area is not new—there are whispers they want access to the maintenance tunnels for reasons beyond mere ore. The Anvil & Ale is both a social cornerstone and a possible hinge for under-city secrets.
