A rugged northern landscape under a gray, cloudy sky.

A rugged mountain range silhouetted against brilliant yellow skies.

Giant black boulders cling to the slopes of a desolate mountain range.

A harsh alien world, with steep peaks under a sky filled with threatening clouds.

A landscape of contorted rock stretched under a greenish sky.

Spiky black mountains rise out of the mist under a yellow sun.

A bleak mountainous landscape under an ominous sky.

Rugged gray-black hills under a dull and hazy blue sky.

A dry, sandy valley under a colorful sky.

A rugged mountainscape under a vividly-colored sky.

Ridged brown mountains rise from a yellow desert under a blue sky.

The sun gleams on the waters of an archipelago of preposterously steep and sharp-edged mountainous islands.
