Oooh, hello!!! Thank you for the ask!! (and also for just following me today! Your sims are very pretty, btw!)
17. Are there any motifs or symbols associated with the character? How are they represented, in their design, personality or in some other way?
Hmmm. Since I haven't gotten to play her yet, I don't 100% know for sure. These things tend to be pretty unintentional on my part, or at least not planned in advance.
However, I do know that she has always had a fire theme going on. It's less extreme in this version than her first version (who was a fire genasi desert storm herald who apparently had a piece of the soul of a powerful fire entity in her), but definitely still present. In this case it's more of a combo fire and sun theme, though, as she was raised in a sun cult, and as a zealot barbarian she deals extra radiant damage. (Though the DM did say my greataxe will also deal bonus fire damage. Man, I love dealing mountains of damage. It's so much fun.)
The fire/sun thing is represented in her mechanical build, but also in her personality and her visual design. (Lots of oranges/reds, and her emotions can be very destructive, especially her anger.) She also feels like it's in her nature to hurt people and/or be used as a tool for the purposes of others, which I think is fitting for a fire-based character.
