I've never seen the point in Openbound, is it just to get to know the Pre-scratch trolls better? I'm really confused, I've gone back to figure it out, but it never really made any sense at all. If it wasn't for Tumblr I wouldn't even have known Porrim existed. (Thank you so much)

Openbound was mostly used to introduce Meenah’s idea of forming a ghost army.  The pre-scratch trolls were kinda popular demand.
