I got the idea when I was looking at rainbow factory pictures and got angry at the fact that everything was rusty, and they clearly didn’t have sanitation, if their goal was to harvest pony blood to convert it into spectra, then they did a terrible job at it as there is blood everywhere (giant waste of resources). After talking about all that I wondered why does the rainbow factory harvest rainbows, surly killing ponies just for rainbows is not their true intentions.
Then after a bit of over-thinking, I made this fanfic: https://www.fimfiction.net/story/371728/spectric-union-harvester-protocall
