The lemurian stone

An enemy force crossing the sea, led by a demon no mortal weapon can slay. Pharazzar's best archers flying into battle on their glorious winged horses, but falling helplessly from the skies. Magnificent palaces of jade and ivory, sundered by war and stained with blood... Such are the prophecies of The Lemurian Stone. Haunted by its visions of destruction, the Empress of Pharazzar must send ger most trusted allies on a search for three unearthly weapons. Weapons which exist far beyond the palace walls—in alternate worlds of magic and danger—deep within the very heart of The Lemurian Stone.
