The dark elf femme fatale Elainuk was the firstborn son of Robert and Lulu Bobblecork. She was born a healthy bouncy baby boy in the shire of Pedstand, which was part of the Cordially Aligned Tetrarchy of Halfling States.
An addition for the Whimsical Flora Codex (based on my Crunalan society in my Dragon Empire setting)
In ancient China, women bind their feet for cosmetic reasons, resulting in them not able to walk without help and walking in a shuffling gait.
Possibly this can be modified such that people do it for less stupid reasons.
Disclaimer: This is NOT a racist remark since I'm Chinese myself and hence entitled to freely judge Chinese customs. NOT sexist either since I'm female as well.
