In an ancient stone circle, a magical halo matrix is activated. Each halo is a portal to a different realm: emerald green to a forest world, deep blue to the ocean abyss, magma orange to a volcano, starry night to the cosmos. Energy arcs between the halos, warping space-time around them. Dynamic, magic special effects, glow effect, fantasy art. Inspired by Interstellar and Lord of the Rings.
