Story

The world was few of beautiful places only if you counted beauty in a sort of conventional sense - grand vistas of interesting geological formations, forests, and such. On a world where the atmosphere keeps visibilty measured in feet and sometimes inches, everyone is blind to the conventional beauties such as they are. On Thinja one had to redefine many things, and beautiful places were among them. Oh, the mountains where there, as were the forests. It's just that nobody could see them. Whereas on Earth the atmosphere is mostly made up of the inert transparent gas nitrogen, on Thinja the inert gas making up a majority of the atmosphere is an opaque one. Well, opaque in the visible part of the spectrum. Radio waves and other such ilk passed through it just fine. But you can't see with radio waves if you're eyes aren't built to do radar. Some argued that life on Thinja would have eveolved these radar eyes eventually if we hadn't showed up and brought all our own life along with us. Hard to see how eyes could evolve that both emit and detect radio waves, but Nature has created stranger things I suppose.

Not surprisingly bats did really well on Thinja, eating up all the poor little native insects who were used to being at the top of the food chain. Bats arrived on Thinja not long after humans, but they've managed to be far more prolific.
