The Shimwalkers are a simple folk. Their only purpose in life is to fit in, to make level what is sloped, to make solid what is shaky. They wander the planet seeking those places that need a little adjustment and force themselves into those gaps, forever, just so our shaky world seems a bit more solid. The Shimwalkers exist in the world with the floaters, a group of beings that drift in the wind. Floaters are more complex than the Shimwalkers, being filled with ideas and aspirations about a fuller life. Blockwalkers pose little threat to the Shimwalkers, who easily wedge between them, but the Blockwalkers seem focused on bringing down the ideas and ideals of the Floaters.
