Umbra Rose is a psychiatrist, that lives in pony ville. He's always willing to lend a helping hoof to help another.
Born far from equestria's coast, he comes from the moonshadow archipelago. A set of islands discovered by a gryphon pirate, Captain Moonshadow.
The Moonshadow Islands are primarily inhabited by Pegasi, Unicorns, Gryphons, and a race of sentient trees, that take the form of stags. The islands are covered in dense forests, and lush vegetation, that these trees protect.
Very few earth ponies call the island home, as its nearly impossible to grow anything in the soil, that isn't native to the archipelago. This isn't aided by the frequent hurricane force winds, and storms that wreck the islands shores every year.
The islands were unfortunately conquered and destroyed, by the Storm king, early on in his conquest. Umbra hopes to go home some day, and help them rebuild.
