A strange and mystical creature, a giant owl with feathers made of sharp, translucent crystals that reflect light in all directions. Its eyes are large orbs of pure gold, radiating a soft, warm glow. The owl perches on a twisted, ancient tree with glowing runes carved into its bark, surrounded by a dense fog that swirls unnaturally. In its talons, it holds a key made of bone, which seems to pulse with an inner light. The setting is a dark forest, dimly lit by bioluminescent plants. Camera settings: aperture f/3.5, shutter speed 1/60s, ISO 400.
