When I was a kid I remember an animated dragon cartoon that was a one shot deal or just a mini series. It was a serious cartoon. One of the events in it may have been a dragon egg hatching and a boy getting the dragon or being protected by dragons in some fantasy realm. It may have been an after school special movie, but obviously not one in which there was a "moral" or anything like the classic "After School Specials". It is NOT the Dragon's Lair cartoon or the Dungeons and Dragons cartoon or "Flight of Dragons".
Can anyone help me find references to it? My internet searches have all been dead ends.
