EARTH Eridanus

Eridanus are a breed of angelic, immortal, nearly-all-powerful equine beings who live in their own dimension, which they created in the image of Earth. They are deeply attuned with the elements, immensely powerful, and come in different elemental 'Strains'.
This horse can manipulate plant growth, rocks, metal, and anything that comes from the earth itself. It can create massive rock formations, even raise mountains, bring plant life back to a barren desert, make dead things bloom, and oh yes, explode things. Can turn itself into stone, or melt into trees to travel extremely quickly. Very sensitive to vibrations within the earth and  extremely agile because of this. Earth Eridanus could be completely blind and still be them most agile and swiftest horses around.
Gender: Up to you
Age: Immortal, about 10 million years old
Height: 17 hands
Additional powers: Will likely drop rocks on anyone it doesn't like, can shapeshift into an anthropomorph, and speak telepathically to humans and animals. Controls plants, rocks and stone, soil, dirt, vines, etc, can run fast, and grow wings to fly with.
Weakness: Not being on the ground. Doesn't mind heat or cold or water or fire--just doesn't want to be any more than three feet off the ground without being connected to it. (As a result, don't try and put it in a horse trailer) Earth Eridanus are usually very placid and calm creatures, but if separated from the earth, it will likely summon some sort of natural disaster. Can create earthquakes, schisms, canyons, mountains, even floods to a lesser extent, so watch out.
