Watch out

A young man with pointed ears and a green tunic stands in a forest, looking at a small, white, floating creature with a simple face, which then flies away as he watches it; the scene cuts to him inside a stone chamber, looking distressed as he speaks, then to him outside in a desert-like landscape, turning to face a large, spiky, flying creature, and finally back to the stone chamber where he is bent over, speaking to the creature which hovers above him.
