Luke frowned at the world laid out below him. Some of the planets they visited looked vaguely like Earth: green, brown, and blue in various places, with white or gray clouds in the atmosphere above.
And then sometimes they were like this one; streaks of reds and oranges across the land and deep mauve seas, with not a cloud in sight. It was just so… alien.
Sure, the Earth-like planets were alien too, by definition, but they just didn't give him the same… uncomfortableness that the really alien ones did.
They were unavoidable, though, so, sighing, he descended into atmo.
