Mad Science Guild

The Mad Science Guild (MSG) is an organization created by mad scientists for mad scientists. They, obviously, aren't exactly sane. Their hobbies include SCIENCE! (The capitals are not optional.)

Nobody knows anything on who founded the MSG. It is said that the creator's experiments are beyond even the comprehension of other mad scientist, and that their inventions must be kept hidden for the good of all lest reality itself crumble away. Whoever created it has nearly no traces of their existence left. Even suspiciously so - they must have suffered an experiment that went so horribly wrong to remove them from this reality itself, leaving only pondering about who they are.

For Science
Unlike their rivals the Rad Science Guild, who merely are eccentric, they're actually absolutely insane. Or their morals are so blue and orange that most people dismiss them as insane, the fools who cannot recognize true genius. Most of their members have absolutely no regard for anything save for furthering their research. Anything that sufficiently screams science such as chemistry, committing crimes against nature, the construction of insanely advanced pieces of machinery, lab scenery construction, and the creation of insanely powerful weapons fits very perfectly into their ranks. If what someone is doing is not sufficiently sciency, then they scoff at it as "soft" science. Who would ever study something as lame as sociology or psychology? You can't do cool mad science stuff with that alone, that's boring! They don't even have Telsa coils!

Policies
Despite their theoretical disregard for morality, the MSG is ultimately a neutral organization morality wise. This is due to the specific philosophy the guild has taken to their work. Although they don't care about morals at all, they at least attempt to play some form of lip service to it. This gets the law off their back and lets most people leave them to their own matters. If they do immoral deeds, they do so under cloak and dagger in secret, using life they created themselves to not get in trouble for kidnapping people on the streets. Otherwise, they use their own bodies and souls as their guinea pig.

Their research often leads them to seek out more unique and powerful entities. Typically those who are the handiwork of other mad scientists out there. However, as dealing with such entities and studying them is often very risky without getting murdered, they take a very specific approach to them. Rather than simply showing up and kidnapping them to strap them to the operating table, they instead propose a mutual exchange of science. If they're able to do their science, they'll kindly let the person know what they were able to find out about them. And by propose, I mean "continuously insist upon it to the point that you get so annoyed that you just let them do it". Not in any threatening way, but in a more weird eccentric one. It's surprisingly effective.
