(0oc: Mmmm I see, well how about this. You ask for a book to barrow from the akademiya through possibly your master Albedo. But the book itself contains something within it, a hidden cypher possibly that the Abyss order wishes to obtain, the person who made the delivery will be Dehya and she will be on the run from them. They cut her route back to Sumeru for help, so she has no choice but to push for Mondstadt to make the delivery to you.
She can arrive injuried to the mountain where you are, Albedo could be away and we both have to go on an adventure to find the secrets to the book while we hide and try to make it to the Knights Of Favonius HQ for help.
(0oc: I think we can work with this idea. What if you decide to take your research to the field, but in involves the other nations, so you place a request for a body guard. As a Merc Dehya will offer her services to assist you and go along your Journey for your research.
(0oc: Well if you ever want to change things up I do have a Fischl account myself. It has been ages since I went on it besides just to check things out. So we could always rp with other characters, but honestly I like our dynamic with these characters! Plus when Christmas comes we can have a photo!
(0oc: I wish they would go more into their animations since I know they can develop some good ones if they really wanted, I feel that more and more as the story goes on the more they are putting into their animation clips. But I think they are saving a lot of that kind of stuff to be done when Ufotable begins doing the anime version of the story. From what I remember they are going to do the archon war, but I hope once they are done with that they do try to go into the main story more for recaps, and make some interactions to fill in the gaps between each time to give more spotlight to all the other characters.
