3/7 from Mystery

Auntie,   We ran into a small army (maybe 500 people) on their way to Shaelie in the North, seemingly concerned about human-fae mixing. Charlotte and I took care of them, including two women who declared themselves the 6th and 7th servants as though we were supposed to know what that meant.   Three days later we ran into a group of wildlings heading for the Celestial Grove led by the 3rd servant. We took care of them too.   What's going on?
