When stone can't stop what grows beneath, the world itself becomes the enemy.
Grimli Stoneheart, last guardian of Dwarrowdeep's ancient forges, faces an unthinkable threat-corrupted stone, tainted water, and the horror of watching fellow dwarves transform into something monstrous. The Verdant Tide rises, a living corruption that devours all it touches.
Forced to venture beyond the mountain halls he's rarely left, Grimli must forge an alliance with those his people have long mistrusted: Thistlewind, a druid with ancient knowledge; Quickroot, a sapling with healing hands; and Harrick, a human warrior whose family fell to the spreading corruption.
As the Verdant Tempest clouds the sky and whispers of despair invade their minds, these unlikely companions race against the tide to find legendary weapons crafted in the mythical Earthforge-their only hope against an enemy that turns nature itself against them.
Some bonds, like stone, must break before they can be remade stronger.
