Today, I caught a glimpse of what the caravaners call the "Endless Dunes". The desolate sea of sand that apparently surrounds the livable portion of the desert on all sides.
Now those dunes can't literally be endless, but it's easy to see why one would think that. Not only do they, stretch on to the horizon, but they're home to get to... get this... giant sand "worms" that will devour anything that sets foot in their domain.
I laughed that off at first. Then I saw a creature the size of a train burst up from the sand and devour a wild morellatops that had wandered into its territory. I suppose I'll just have to learn to walk without rhythm...
