* {{Defictionalization}}: [=McCaffrey=] worked with real-life musicians to produce at least [[https://www.opland-freeman.com/harperhall/index.htm two albums]] attempting to depict Perrnese music.
* DevelopmentHell: 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.
* ExecutiveMeddling: 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.
** Specifically, in 2002 writer and producer Ronald D. Moore had written a pilot script and sent it in for network approval. The production was mere ''days'' from shooting the pilot. When the script was re-written, Moore objected to the new dialogue which felt more in line with Buffy the Vampire Slayer than the source material. Eventually the network agreed with Moore and pulled the plug.
* FanworkBan: 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.)
* ScienceMarchesOn: 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.
