@monsterblue Ah, yeah, that was the story from Pluto. Few people ever really took me up on roleplaying Plutonians, but the couple that did were pretty interesting.

They were basically an equine-centrist religious cult inspired by and named after the ultra-rationalist horses in Gulliver's Travels, Huoyhnhnms.

Electric Keet did a lot to elaborate on them, so this isn't all my worldbuilding, but basically they had gotten hold of some semi-forbidden nanotech from [REDACTED] Terran [REDACTED] and used it to TF people into "objectively superior" pacifist equines under the aegis of a pseudo-medlcal "clinic" on Pluto. The implications were deliberately kind of horrible and were mostly intended as an excuse for a lot of dark medical kink. :3.
