The Heart of the Blight

After what feels like hours of wading through suffocating rot and choking spores, the forest finally opens into a grotesque clearing. The canopy here has torn itself apart, revealing a sickly, gray sky mottled with swirling black clouds that pulse like bruises.

At the center stands a towering, ancient tree, larger than any you have ever seen. Its bark is cracked and blistered, with thick veins of black sap coursing beneath the surface like poison through a wound. The tree’s roots spread wide, sinking deep into the earth and twisting unnaturally, breaking the soil into jagged shards.

Around the base, the forest floor is a tangled mass of fungal growths, thick mats of pulsating spores, and thorny vines that coil and twitch as if alive. The air here vibrates with an oppressive energy—a dark, living sickness that presses down on your mind and soul.

This is the source of the blight.

You see that embedded deep in the heartwood of the tree is a black crystalline core, pulsing with a faint, malevolent light. It hums with corrupt power—an alien force twisting the forest from the inside out.

Your guide’s voice trembles as they remind you: “The salve you carry—this is the only hope. You must reach the heart and apply it directly to that core. If you delay, the blight will consume all.”

But the forest does not intend to let you pass unchallenged.

🗺️ Encounter Overview

The party enters a clearing dominated by the blighted world-tree, corrupted by a malevolent crystalline heart. The forest fights to keep them out: vines lash, fungal clouds choke, and terrain shifts like a beast in pain.

A corrupted Treant—the forest’s twisted guardian—rises to defend the tree, imbued with unnatural vigor and rage.
