How to get there: The signed woodland cave southwest of Pioneeria, near −659, 524. Descend to the safe southern vestibule.
Three prepared adventurers are recommended. Bring a light and supplies, read the warning board beside the ladder, then enter the northern circle together. Dodge branching roots and the great bough; destroy three amber knots to expose the heart. A tank or mender can help, but no calling is mandatory. Players cannot fight each other here.
Earned rewards wait at the central Heartwood altar after victory, including after death or logout. Additional helpers share one fixed reward pool. The ladder remains a retreat.
