The Many Ramblings of K. A. Webb

>>Life clay is only found on Athare, created by the world in an attempt to gather up ambient magic. On the day the fae stumbled across it they believed it was just normal clay, until they started trying to make things from it, and a newly made pot attempted to walk across the room.<<

This made me think of a favorite Mullah story:

I would love to see a World Walkers retelling of that.
