Thanks to the thread about "Cultural Approbation" I'm working on new societies for my games again. Now I'm curious, what societies and subgroups of well known races have been created by everyone? How much did you mix up existing ideas (especially existing human culture and stereotypes) and how well did it go over with your players?
Lots- looking at what I designed for my homebrews as well as helped other gamers for THEIRS, here are some faves:
1) Minotaurs who had a Plains Indian style culture, using chariots instead of just riding horseback (due to their size, of course)
2) drawing inspiration from the novels of Kurt R.A. Giambastani, used the Plains Indian cultures (again) to help a fellow ENWorlder create a tribe that used moas and/or other large flightless terror-birds instead of horses & dogs as steeds and hunting animals. Almost used velociraptors (like Giambastani did), but thought the birds were more fun.
3) fused typical "Dwarven" societal structures with the river culture proposed for some setting's halflings, and used that for a society of anthropomorphic snapping turtle folk. IOW, long-lived, short, powerfully built critters with a mercantile river society, strong family ties, and a string warrior culture. Also, a touch of Romani was thrown in the mix.
4) in a post-apocalyptic fantasy setting, the elves were very few in number, and had used magic on themselves to permanently make them part plant in order to survive. They lived mainly in partnership with the equally rare Inheritors, psionic Dwarves culture whose normal bodies were all replaced by psi-powered bio/mechanical ones that housed only their brains and a few key organs. Think fantasy Cybermen or Daleks.
5) aquatic elves who had used ancient magic to permanently add both chromatophores (to change colors like Cephalopods) and nematocysts (to sting like Cnidarians) to their bodies.
6) alien "Grays" who used their technology to appear as "elves", cast "magic", and create stasis fields ("time passes differently in Underhill...") while trying to survive long enough to be rescued from crash landing on a typical fantasy world.
7) Drow who were drawn to the black widow spiders more than any others, and were EXTREMELY matriarchal. And cannibalistic.
8) size S Thri-Kreen who flew like dragonflies and could communicate via bioluminescence.
9) earth elemental dwarves who carved themselves from stone, with the stone type determining what their abilities were. In a very real sense, their abilities were "set in stone", with constraints on what classes they could take based on their origins: Dwarves from metallic ores could be warriors or clerics, but were not able to be rogues or any spellcaster affected by ASF. Those from gemstone matrix were arcane or divine casters, and were too delicate to be front-line fighters. (Yes, this all made them subject to kidnapping plots, too.)
10) I reworked the various Planetouched of 3.X into the Nephilim- essentially a broad template covering any sentient being who had some otherplanar ancestry.
11) using the Seshayans from Alternity as the unknowing and scattered remnants of the fallen lords of a vast and powerful Underdark empire. They are mostly meek as a rule because of their small size, stature and outsider status, until evidence of their former Empire is unearthed... Real boogeyman stuff.
For those who haven't a clue as to what Seshayans are:
...and many more.
