Spectral Undead Guardian of the Haunted Forest

Eerie undead creature emanates supernatural green energy in a dark, twisted forest landscape, capturing the essence of gothic horror fantasy art.

A terrifying skeletal creature emerges from a dark, misty forest, bathed in an intense emerald green glow. The undead entity stands menacingly among gnarled, leafless trees, with a luminescent core pulsing at its chest and an otherworldly aura surrounding its decaying form.

The creature is composed of decaying organic matter, with skeletal limbs extending into sharp, claw-like fingers. Tattered, moss-like vegetation hangs from its form, blending with the surrounding forest. Its skull-like head glows with an eerie green light, and its eye sockets emit an intense, supernatural radiance.

The image evokes a sense of dark fantasy and supernatural horror, representing a powerful undead entity that seems to be both a guardian and a threatening presence within its mystical woodland domain.
