( a small adult is correct. technically he's a created human who doesn't have a hard limit on age which makes it a bit complicated. he's much older than he looks although his demeanor lets on to the truth. )

My studies vary. Currently at home my major area of research is the Dragonspine region of Mondstadt and the truth of the world. I do not hold myself to any one area if something piques my interest, however. ( he's interested in a little bit of everything. ) In this place I'm currently examining this fog. The properties that "take" things and then allow them to be returned are fascinating. I wonder if it could be bottled up and taken elsewhere?
