Gravity
Gravity. The mysterious force connecting all objects, its inexorable pull what makes planets spin and solar systems move-
But you know the truth, don’t you? Children always know what their elders repress. You see the tiny figures running about on the floor, so infitesimally small that adults, with their heads so far off the ground, don’t notice them. Children however - ah, children have sharp eyes, and can see the gravitarians with their precious hooks. Did you know that each gravitarian can lift up to two million times its own weight? But of course they don’t use this power for lifting. It’s all about pulling.
You have watched as their hooks dig into the sole of a shoe, dragging it back towards the ground as you walk. I’m sure you’ve seen the gravitarians hanging on desperately as an airplane strains upwards against their grappling hooks. If you’re especially observant, you’ve probably seen grappling hooks from other worlds, Solar gravitarians and Martian gravitarians all straining and heaving and gasping as they pull your planet in neat little circles.
Don’t bother the gravitarians - they have a hard job. But when you grow and your head gets so far away from the ground that you can’t see them anymore, do them a favor and remember who prevents you from floating off into space. They could use the encouragement.
