Cultures/creeds For A Gonzo Transhuman Fantasy Setting Constructed Entirely From Repurposed Dungeons

Cultures/creeds for a gonzo transhuman fantasy setting constructed entirely from repurposed Dungeons & Dragons tropes:

A community of serial reincarnationists under a permanent enchantment that causes them to eventually reappear in a new young adult body with personality and memories intact any time they’re killed, whether through violence, disease or old age. The exact form the new body takes is random, and is as likely to be an animal as a humanoid; their cavalier attitude toward death is tempered by a strong cultural expectation to learn how to live with whatever body you end up with, so it’s not uncommon to encounter - for example - a respected member of the community who currently happens to be an owl. Socially they tend toward agrarianism, though they have no particular objection to urban living; in their ethos, a sprawling city differs from a bird’s nest or a beaver’s dam only in scale.

A mob of undead skeletons obsessed with the transitory nature of existence. Their culture is dominated by short-lived art forms, like sand paintings, improvisational music, and elaborate wooden sculptures which are burned on completion. They’re able to freely swap bones with each other, or replace them with suitably prepared substitutes taken from non-undead skeletons or carved from wood or other dead organic matter, and it’s not uncommon to encounter a skeleton with none of their original bones remaining; pondering the resulting ship-of-Theseus problem with respect to personal identity is regarded as a fun intellectual exercise, but it doesn’t actually bother them. Alone among the creeds, they never directly produce new members; every one of them is a former member of some other creed.

A society devoted to the pursuit of knowledge by transforming life forms through experimental wizardry. They regard experimenting on others - even animals - as horrifyingly unethical, and as a result, each of them uses their own body as a testing ground. Individual members range from mostly human with only a few odd physical quirks, to entities not readily recognisable as life, let alone people. While novel transmutations are always self-directed, they’re willing to perform the most thoroughly tested and proven procedures on others with informed consent, a service that comes in high demand. Likewise, interventions to rescue other members of the creed from experiments gone awry are permitted, though only after careful deliberation - after all, perhaps your neighbour meant to spend a year as a rock!
