I want to give you some information about AS world so you could become familiar with its 'inner working'.
'Antique Store' is a place where 'Heavenly Spheres' collapsed, causing countless disasters for humanity and numerous problems for the secret and not-so-secret societies and organisations which maintained supernatural order. Magic, spiritual energy, and, more importantly, Ephirite became exposed to 'normal people', along with other things and conceptions which were treated as 'fairy tales' before. Without control 'from above' all this crap poured on people's heads. There was no 'soft transition' - everything happened too fast for humanity to adapt, which caused even more panic and social/cultural/other tensions and conflicts. And the main theme of those conflicts was religion.
At first people shrugged their shoulders and said something like 'Yeah, there was God after all. So what? Now He's gone, so why bother?' But later some people started to ask each other one inconvenient question - what now? And what should we do with religions? Three major 'philosophies' appeared: stubborn 'hardcore' believers, seekers of a 'new way', and those who had no interest in all that crap. Some people thought that those were aliens, and that Ephirite was brought to Earth by meteorites or because of alien activity, refusing to believe that those events were supernatural in nature. It was a relatively 'calm' situation, until 'Celestials' appeared. It changed many things. 'Celestials' named themselves differently, but they had one origin - 'Heavenly Spheres' became too unstable and dangerous for them, so they decided to go to Earth. It was no 3'rd century BC, and people were no naive idiots, so instead of 'returning of the 'Old Gods', celestials chose another, more subtle approach, and silently integrated themselves in society. Besides, they were not 'powerful' and 'almighty', especially after the beginning of a world-spread 'Ephirite' program, when bright scientists all over the world started to push Ephirite science forward and invent anti-F weapons, scanners and other things to protect humanity from F-creatures and other supernatural dangers. So celestials worked from the shadows, trying to calm and remedy the situation. At least some of them tried to do so. Not all celestials were good, and not all of them wanted 'world peace'. That's how MSB was created. It was formed to watch over humanity and protect it from F-creatures. It wasn't a 'secret society' or some fancy elite club. It was an official organisation, with statutes, uniform and jurisdiction. Speaking of which. MSB worked from the position of force, and operated without any constrains from the side of the government. The only nominal 'master' of MSB was The Church, but relationship between those two was strained and complicated.
The Collapse caused the biggest catastrophe in human history - Ephire War. Some celestials weren't pleased by their positions among humans, and decided to become rulers of mankind. The war was waged for 8 years, and in the end little was left from the world as people knew it. Huge territories were polluted by raw Ephirite, F-mutations changed flora and fauna, Moon changed its orbit because of the failed 'Gateway' program, millions died, and many other terrible things happened. The whole 'Pyramid' continent was polluted to the point that it got the name 'Forbidden Land', and all communications with it was ceased, plus military forces were placed around to prevent anything from breaking out. People started to live in big overcrowded cities and badly-protected refugee camps, political and economical situations were terrible, and there were no signs of improvement for any of those problems.
That's the world of 'Antique Store'. It's a bad place to live in, but people struggle and try to rebuild. Some - because of hope, but most of them - because they have no other choice.
