For as long as there have been sentient beings in the Milky Way galaxy, there have been tales of mystical gems. The Sacred Heart of the Universe is one such gem -- but not just any gem, but the most powerful of them. When Sabour Monitor Rebani Kalba comes across one piece of the Heart, it sends him on a quest to find the other fragments. Along the way, he meets a number of unusual beings, among them Bal Tabarin, half-adventurer and half-archaeologist. Together they must piece together the puzzle of the Heart of the Universe -- even as others race to do the same!
