Maud Pie Beats Up Some Rocks

It's a story about Maud Pie beating up some rocks. The title says it all, really.

One is a pair of ancient magitech artificially created gemstone-mounted intelligences sharing a hardlight body fused together by mutual hatred and driven mad by their own self-imprisonment under the endless waters that they are capable of controlling, towering a good eighteen feet tall.

The other is a tiny gray horse.
