They were not part of any system that he had going that was normally in place to keep track of people. Even though they were aware of who they all were could not be everywhere at once thus they were able to find a place to stay for the time being at least.
Rangi then managed to get the princess armor off of him somehow. He learned what it was called when his mentor Dagger woke up and noticed it herself. She noticed there was now a large scar on her chest and her humanoid form was displaying the crack that was in normally.
