Okay here is how it is going down for the first part:

It is a mystery.

But seriously, the characters will not know what is happening until they start looking and moving around. The road to the boss isn't too long, but there might be clues along the way. To tag, reply in the tag's title what they are doing.

Also make sure you have your character's persona info up to date and link it here as a reply so I can easily access it. Thank you and have fun!
