Dragonborn for example seems like it would be the perfect DLC to teach the PC how to create scrolls...we know that there is at least one telvanni tower and a bunch of people think Fyr is back from the trailer. Perhaps one of the things the PC will learn how to do in the course of the DLC is to create spell scrolls. Just a thought I'm still quite curious if there will ever be a use for these items and I think learning from a master wizard would be a great way to have the character learn a proper use for them.
