Giant Worms

Giant worms live on Dragon's Foot and were created by Phystene to convert rock to soil and to keep soil fertile.
'She wanted something that would turn rock into soil and, later on, help keep the soil nutritious for plants. It would be a worm of some kind, ...First she took a normal earthworm and enlarged it till it was several meters in length. She then began changing its structure, giving it bones and a functioning jaw strong enough to crush even granite. She then altered its digestive system to allow it to break down rock. Lichen and moss that would grow on its back would also help the worm do this. She then granted the worm sharp teeth that her harder than the strongest steel. While large molars would be better to grind rock down, the sharp teeth would allow it to break bone, meaning it could also act as a scavenger once other animals appeared on the continent as well as help it fend off predators later on. Even with their strength the act of chewing on rocks would wear the teeth down, so Phystene designed it so the teeth would regularly fall out and be replaced with new teeth. ...The worm was... fairly ugly. ...Content with her creation, Phystene used her power to create more of them and jumpstart their population. The worms wasted little time, burrowing into the rock with ease. They, allo[ng] with the lichen she had already created, would surely turn the barren continent into a fertile land.'Phystene creates giant worms - https://www.roleplayerguild.com/posts/4844931
