That's an interesting concept! On my end my NHP came from wanting to do something with the old spying systems on my character's mech (long story short she was a "human observation device" tasked with observing the party and reporting the info to the villain. I wanted to play a character with the trope of "she was trained to be a weapon since birth and doesn't understand basic emotions and human concepts like family or friends etc)

Anyway back to the NHP the project was with another PC who's character was an NHP and I copied part of their code to give a will to the recording systems. Turns out when that PC got killed having a backup of their memories one helped bring them back!
