Centuries ago, twin brothers built a castle in the Dragonspine Mountains and established the prosperous town of Verdigris below it, but the mage Eldamar's obsession with immortality led him down a dark path toward lichdom. Unable to slay his own sibling, the paladin Oswulf enlisted a legendary band of adventurers called the Silver Blades to help contain the transformed Dreadlord, and together they drove back the ensuing wave of monsters through a desperate magical solution: a glacier that froze the entire valley in stasis. When dark cultists known as the Black Circle shattered the spell centuries later, the thawing ice revealed rich gem mines that drew new settlers to the rebuilt town of New Verdigris—but with the ice came the monsters, awakened and hungrier than ever. Summoned by the Well of Knowledge through the desperate wishes of the townspeople, adventurers arrive to find the mines overrun and the survival of New Verdigris hanging in the balance.
