I somehow missed this whole thing when it started and I only now started to read it through but I have not read the whole forum because it started to get overwhelming and might have missed something because of that. But anyways I wanted to give my own thoughts because I spent so much time reading 😅
I had a few different ideas what might be happening but I think this is where I stand:
Seraphine and Cirrus are behind all the cryptids that we have been getting. There is a few possibilities how this is:
-They were kidnapped by the cryptids and somehow made friends with them
-They are looking for and capturing them for us (I think this is least likely)
Or the one I really think happened:
-Seraphine is cryptid shape shifter (kinda like a werewolf maybe?) and Cirrus is covering for them.
Maybe Seraphine can usually somehow manage to stay in their cat form. Like forcing the sift not to happen. But suddenly and unexpectedly they loose control and end up in their cryptid form unable to change back. Panicked and unknowing what to do they kidnap Cirrus to ask for her help (in this scenario Seraphine has a full or almost full control of their cyptid form, not like most of the werewolf stories where the sifter looses most of their control at the moment they sift). At first Cirrus was in a panic but after Seraphine had convinced her that she was safe and that the creature before her was indeed Seraphine they start to look for a way to get Seraphine back into their cat form. Looking for a "cure" took time and thus they send cryptid creatures to the camp for us to find so that their disappearance wold attract less attention. There are still a lot of people that are worried of them of course, some of them try to minimize their worry in front of the campers to not to worry them and some of them show their lowered spirits in front if us more easily. The cryptids are actually very nice and only misunderstood because all the scary stories there are of them so they help up Seraphine very gladly. They have always lived around the camping grounds but usually they don't show themselves to people in fear of a bad reaction. Seraphine and Cirrus probably faked many of the evidence to keep us from finding the truth. Seraphine not believing in cryptids would also be a cover up story so that they wouldn't seem suspicious. Some of the chaos would still probably be the cryptids around the camp, they don't really know how to interact with people and I'm not sure how animalistic they are. When they finally got Seraphine back into their cat form they came up with a cover up story with some truth sprinkled in to hide their tracks.
The reason why I settled into this story is because there is motive and explanation to most of the things.
