- Development Hell: The Live-Action adaptation has been stuck in it since 1995.
- With Warner Bros. having bought the film rights in August 2014, there might finally be hope.
- Executive Meddling: In a rare inversion of the typical trope, a studio executive actually stopped production of a TV series based on the novels a few days before shooting due to lack of fidelity to the source.
- Fanwork Ban: The author was legendary for her adamant opposition to fanfic, and while she permitted roleplaying games, attempted to exercise editorial control over what could be done even in people's individual RPs. (The latter was less successful; even today, "pink dragons" are something of an in-joke in the fandom.)
- Science Marches On: Pern was available for colonization due to its lack of resources, categorized as metals and fuels, which would in theory preclude an industrialized society. This motivated the creation of a biological Thread-fighting solution in the Dragons. Forty years after the first books were published biofuels, high strength carbon composites, bio-engineered fibers and all manner of other scientific advances would make a highly industrialized society on a traditionally "resource poor" world not only possible, but also environmentally sustainable.
- Technology Marches On: Millennia in the future of our day, the world of Pern is finally saved with DOS. An AI version of DOS, but still...
- What Could Have Been: In The Masterharper of Pern Robinton is noted to have the ability to speak to (and hear) dragons, leading to his mother actually hoping that he would be Searched by a Weyr in order to get him out of their troubled home. Unfortunately no queens were laying when Robinton was of the optimal age to Impress a dragon.
