So the name "Space Monkey Mafia" definitely has an Ijad vibe to it for me. I see a clan, or at least the core of the clan, of Ijad bonded with creatures that resemble terrestrial monkeys but may not be actual monkeys. I'm still trying to process this element.
Now I'm not saying this is a criminal group, just that the word "mafia" has expanded in use as slang to denote a group of people joined in a semi-secret manner. Even though we generally don't discuss criminal elements in MFZ. Crime is a result of failing economic policies and since the Solar Union is a failing empire there would be criminal events happening. Also, this name doesn't have to be the real name of the group. It could be a derogatory nick-name an outsider used to refer to the group and it stuck. "We just got screwed again by that +@#$%&* Space Monkey Mafia!" I'm sure we've all had experiences with stupid nick-names that wouldn't go away.
I see this moniker as a callback to old school science fiction and the early days of the space race. Now all I have to do is build some Frames for this faction. I hope you enjoyed this little interlude, they don't come along too often. I guess you could see this as a reason to be open to moments of creativity and to try and make the most of them.
