Castaspella

Adora
Glimmer mentions to Adora that Castaspella is 'a bit much' just before she meets her. Adora was invited to go site seeing in her kingdom and after being tormented by Shadow Weaver, who was hiding around the castle, she turns into She-Ra and accidentally destroys 1,000 years worth of inscription. Castaspella blames her for damaging the work until Shadow Weaver attacks the group and nearly takes over Mystacor. When she stops Shadow Weaver and kicks her out of Mystacor for good, Castaspella forgives her and tells her that she'll knit her a sweater.

Angella
Angella and Castaspella are sister-in-laws through Micah. It's unclear if they have a good standing relationship, but Castaspella does write to Angella and she 'never writes back', according to her.

Bow
Castaspella likes that Bow is best friends with Glimmer and was excited when he started to visit; she thought Glimmer had made him up. Bow has received socks as a gift that she had him; something he brings up when Adora, Glimmer and him visit Mystacor.

Glimmer
Glimmer is Castaspella's niece. Glimmer describes her as 'a bit much'; asking too many weighted questions and insinuating things about her life. Castaspella will mention to her any chance she gets that she need to start visiting more and make more friends.

The Horde
Castaspella holds a lot of hate toward The Horde, since they killed her brother and took away Light Spinner. They continue to attack lands around them, but thought that they couldn't get to Mystacor; until Shadow Weaver followed Adora in and almost took control.
