Buer is one of the many unfortunate drones that work under Asmodeous. Specifically his janitor. He didn't mind it at first, he was built for it, after all, but then the dissections and other unsightly experiments began, ones he was forced to clean as well. At first, he was repulsed, but soon he eventually grew used to it. Nowadays, it takes a lot to phase this old drone. It's not a job he's proud of, quite the opposite in fact. He quite resents it, but rebelling would basically be a death sentence. So he'd rather stick with living a somewhat uncomfortable life rather than fighting for it everyday.
