Craft a scene within a medieval castle's great hall, where knights gather around a massive round table, discussing matters of chivalry and honor.

Desert oasis at twilight, with palm trees, a tranquil pond, nomadic tents, and camels resting under a starry sky.

A vibrant sunset over the ocean waves.

Glistening icicles hanging from a frozen tree branch.

Mysterious alien landscape with bizarre plants, floating rocks, a glowing river, and a distant spacecraft.
