Hey there! I have a youtube channel where I dedicate a lot of time and effort to Game of Thrones/ASOIAF theories and information videos. I even have a series dedicated to ASOIAF characters who don't appear in the show and am actually looking for feedback on characters people would like to see videos made about. That particular series is called Spotlight but as I said I make A LOT of Game of Thrones/ASOIAF content.
Hope you can check it out. The link is https://www.youtube.com/channel/UCG5X_PT2ZixOJ1lymOFOOzw
