This was made in 1988 or so. It references the Castle Amber module, The Order of Light from Gemstone III, and Louise Cooper’s the Time Master Series, plus the city of Charn from my home brewed campaign.
The punchline to many of these references was that the characters AND players were aware of all of these references as works of fiction. The characters had copies of the Time Master Series and Averoigne stories. Each character has ring of wishes to enter the stories themselves.
When I was in high school, this seemed like a great hook.
