Long ago in a distant land, I, Nightmare Moon, the shape shifting mistress of darkness unleashed a never-ending night! But, a foalish pony warrior, wielding a magic stone stepped forth to oppose me! Before the final blow was struck, I tore open a portal in time and flung her into the future, where my darkness is law! Now the foal seeks to return to the past, and undo the future that is Nightmare Moon! (FiM/Samurai Jack fusion)
