Blackstar was an animated fantasy series done by Filmation, who went on to create He-man and the Masters of the Universe and She-ra, Princess of Power. In fact Blackstar seems very much like a warm-up for He-man; the combined science fiction/fantasy atmosphere of Sagar would be reborn in a new form in He-man's Eternia, which would end up getting developed a lot more deeply because He-man ran for something like 130 episodes and Blackstar ran only 13. I last saw this series in the early 80's, and I still vividly recall it with wonder. It was a true epic fantasy. I highly recommend it if you can find it on video somewhere.
