Platinum Cross was one of the greatest physicians known to pony-kind during his time. He was the stallion to go to for any bodily ailment. He could cure the sickened, mend shattered bones, and even save a life from the brink of death. He was revered as one of the greatest healers in Equestrian history, and one of the founders of modern medicine. All of this was overshadowed by his discovery of what may have been the greatest spell ever inscribed upon a rune.
A spell to bring the dead back to the realm of the living. One would think that such a spell would be a boon for ponies everywhere, able to see and speak with their lost loved ones. But that was not the case, for the ponies of his time were wary, and superstitious. They saw him become nothing more than a monster, a practitioner of the dark arts, if you will. He was forced into banishment, and neither coat nor tail was ever seen from him again.
However, when a pony bearing a suspiciously similar look to his is rumored to be living in the Everfree, a certain group of fillies become very intrigued. Things can only get better from then on, right?
