You look at a skinny girl, standing 5' 5'' tall and having a roughly average appearance in general except for her bright red hair. Brown eyes and white skin completes her general despiction.
Wednesday furthered her learnings during the year after her mother's death. She's now 17 and able to use a couple of spells more than she was before. Her choices tend to be non-harmful, focusing on enchantments and illusions mostly and forcing people to fall asleep or blinded to be the go to solution when the needs arises.
All the knowledge she possesses are a mix of her upbringing and recent experiences, which may be the reason why, while cheerful and open-minded, she's also very wary of her surroundings, something that should be noticeable by most of the people that interact with her for the first times.
Karen is Wednesday's childhood friend, a bright girl who attended the same tasks Wednesday's mother recommended her to. At first the relationship was rather insipid, but as they were the only girls around the same age they soon became friends.
Their friendship continued to be strong throghout the years, and it looks like it will be one that will last for years as Karen is very fond of Wednesday, and she looks to see the day when Wednesday becomes someone important in the realm, as for some reason she believes - and hopes - that Wednesday will become someone worthy to follow.
