"Dreams of a Dead Castle"
In the heart of old Ponyland there was a fertile valley not very far from the coast of the Ocean of Dreams. It was once a serene place of such bucolic pleasures that the ponies who lived there even called it Paradise. Over many years they planted vineyards and built handsome buildings out of the lovely rose-streaked marble blocks they took from the ancient and overgrown ruins they found under every odd hillock in their peaceful valley. Generation after generation grew old in the evening shadow of the great mountain at the head of their valley. But then, one night, the idyllic merriment of a Summer's evening was cut short by a thunderous roar that shook the earth and froze the blood of the little ponies. From the mountain, a column of incandescent fire rose to pierce the sky, as burning stone fell like rain. By morning, Paradise Valley was no more, buried deep under volcanic ash.
Of those who survived the cataclysm, only one ever returned to that place, the old Pegasus mare Lady Paradise, who had been the feudal ruler of the valley. For many years, she lived alone among the blasted ruins, belligerent to passerby and of unsound mind.
