A robed figure with a glowing staff stands at the edge of a moonlit forest clearing, confronting a colossal tree spirit whose face is carved into ancient bark. The tree spirit's eyes are hollow caverns filled with swirling green light, while moss and luminescent fungi cover its deeply grooved bark skin. Gnarled root-fingers emerge from the earth around the clearing, each root thick as tree trunks and covered in bioluminescent lichen. The figure's staff casts blue-white light that illuminates floating spores and magical particles drifting through the misty air. Towering oak and pine trees form a natural cathedral around the clearing, their branches intertwined overhead to frame the full moon. Fireflies dance between the roots while the tree spirit's mouth opens to reveal rows of wooden teeth and a throat that glows with amber light.
