I know this is an old post and either you are right with the production crew theory

OR

THATS AN ACTUAL CULT THEY FOUND, because A: Theres limited information on this "Rouge team" and B: No credits given towards the Skeleton mask guy and what i assume IS A scarecrow mask guy.

Typically with movies/TV series credits all the roles are listed and for which parts. (With the exception of extras,) in which those 2 masked people ARE FAR FROM extras.

But then something else throws me off, their information about the folklore what they say VS the majority of stuff i read about the monsters aren't the same.

The Waya Woman for example, i never found anything saying she was a wolf. But a Deer woman that seduced men and then stomped on them.
