Some shards that have been able to transform the people into a bunch of mythical creatures, but there were some that have not been found, and instead grew to the size of stalagmites to where they poke out of the ground of any substance, whether it's the grass, in a cave, in the sand, or even on the ocean floor.
Many archeologists have quit after not finding them for so long, and haven't bothered looking for them for so long, that they gave up on them, after the investigation. So the scientists left the stalagmites on the ground alone, waiting to be found by anyone who goes near it. Little does humanity know, is that when the sun reflects upon the giant shards, they cast a ray that makes people fuse become the creature they chose them to become, while remaining on the ground.
