Dimensional Key in a Hidden Lagoon - Concept Art

Ultra-detailed concept art of a hidden lagoon at golden hour. Crystal-clear turquoise water, surrounded by moss-covered rocks, hanging ferns and bioluminescent algae that glow softly. In the center, a dimensional key floats above a weathered pedestal carved from coral and driftwood, inscriptions in alien runes glowing cyan. The key itself is ornate, with fractured facets and a handle resembling a miniature cosmos, with tiny portals visible inside its blade showing miniature landscapes and distant starfields. Mist rises from the water, a tranquil waterfall in the background, cave mouths opening behind, and sunbeams piercing the canopy to cast dramatic shafts of light. The scene feels otherworldly and inviting to exploration. Color palette includes teal, emerald green, gold and violet-pink highlights. Style is fantasy concept art for a video game, ultra-detailed, cinematic lighting, painterly textures, high contrast, deep depth of field.
