There's three of the monsters, so I wasn't sure who was with which specific one. However, from what I gather(correct me if I got any of them wrong):
1. Vitcus, Millicent and Hainer are at the same location
2. Fatima and Amalia (I believe they are targeting the same one?)
3. And Keetas is hiding out nearby
Hainer hasn't noticed Millicent hiding out yet, but if you want her to interact with any of the characters, feel free! Also, you guys are all allowed to control and attack the monster however you wish, I don't have a rule on that, in case any of you were wondering!
