This Power-Set allows you to create characters that have powers over earth and stone (or sand or lava). Characters with powers from this set might be made of rock, lava or sand, be able to telekinetically control chunks of earth, be able to create things (and helpers) out of Earth or even move through the earth as if they were swimming.
Powers in this set include a possible Elemental Mastery which makes other powers in the set more interesting. Let us know if you like this, or if it makes sense.
