The image depicts a person cosplaying as Triss Merigold from
the video game "The Witcher 3: Wild Hunt". They are wearing a brown leather outfit with belts and armor, and they have short
red hair. The setting appears to be an old-fashioned library or bookshelf room, which fits well with the character's scholarly background in the game. Triss is a witcher who has knowledge of various
magical abilities and potions.
