In the bustling streets and shadowed alleys of Waterdeep, ranger Sereggul Bladesong and his clever gnome companion, Gawin Wildbelch, are drawn into a dangerous web of gang wars, political schemes, and ancient secrets. When a devastating fireball strikes their home in Trollskull Alley, the trail leads them deep into the city's underworld—through sewers, criminal hideouts, and the lair of the beholder crime lord, Xanathar.

With the aid of the enigmatic elf wizard Angaea Loreael, they recover the fabled Stone of Golorr—only to learn it is the key to a hidden vault containing half a million stolen gold coins. But the vault is guarded by Aurinax, an ancient gold dragon bound by an oath to its former master.

To see the gold returned to the people of Waterdeep, the companions must outwit powerful enemies, survive treacherous alliances, and face choices that test their will, loyalty, and courage.

Rich in intrigue, danger, and camaraderie, The Vault of Dragons continues the epic journey of the Bladesong Chronicles, where wit is as sharp as steel, and every choice may shape the fate of a city.
