An organic nightmare of pulsing wood and damp peat beneath the Rotskogen forest. The dungeon consists of living chambers connected by hollow, vein-like roots that pump dark fluids throughout the complex.

The air is heavy with the smell of wet earth and copper blood. A low, rhythmic thumping vibrates through the floor, while bioluminescent spores provide a dim, sickly red glow.

☠ Threat

The Crimson Saplings cult, led by Arch-Sapling Vane, seeks to corrupt the Heartseed completely using the Blight-Kernel. Their presence has caused the forest to rot from the inside out, as they siphon life from the land to empower a forgotten, earth-bound deity.

History

Once a sacred grove, the Heartseed tree's roots were occupied by the Crimson Saplings cult. They hollowed out the Great Tree's foundations to create a site for blood-tithes, turning a natural wonder into a biological machine for necromantic rituals. Now, the tree is kept in a state of perpetual agony to fuel their dark magic.
