The still surface of a pond, broken only by the leap of a single frog.
Underwater Atlantis-like city with ancient ruins, bioluminescent sea life, mermaids, and a bubble-like protective shield.
A vibrantly colorful galaxy, filled with a multitude of stars and cosmic dust.
Ancient library with towering bookshelves, hidden alcoves, a grand central atrium, and soft light filtering through stained glass windows.
