AH-96-B3 was a dutiful maintenance droid. It always finished it’s work on time and never complained about bad oilings.
But one day it malfunctioned. Somehow it aspired to touch a butterfly. A notion it’s controllers could not understand. Ah-96-B3 was not designed to have such fantasies. So it ended up scrapped, recycled, laying on a waste pile outside town.
Which is where a butterfly landed on it’s fingertips.
