Cas did not gain the height of her aasimar side, but rather the shorter stature of her human side, standing around 5’4”. While she may be shorter, she carries the leaner grace of her angelic half, small but not weak in the least. She is built for speed and grace, often finding others enticed by the way she moves, though chooses to ignore it. Her deep black hair falls straight at the sides of her face, framing the soft features and emerald eyes. One does not expect her eyes to be that unique given her darker and more mundane features, and they often catch people off guard not knowing she had some angelic blood in her. Her lithe form is usually dressed in formal militaristic uniform that she had taken from a captured soldier years ago, but then there is often a floating miniature beholder eye hovering over her head. She shaped her spiritual weapon in a form of a miniature beholder since she finds beholders cute and makes the ignorant or uninformed think that she has a infant beholder with her.

Dyed her hair recently to white and changed her clothes something she picked up while staying in Dene. somewhat still similar to military outfit she took form her previous victim but this one was more comfortable for her. Where she found it is anyone's guess.

Cas can be charismatic when she puts her mind to it or when in the presence of her father,  such as when negotiating in business, but she suffers from the combination of being easily bored and self-impressed. She often comes across with a smug, amused self-confidence that easily rubs people the wrong way. She's also pretty lazy, and with servants to tend to her needs, tends to spoil herself. She's far more cruel than her other siblings and would always tend to 'un-alive' servants or slaves alike when these gets too bored with them. When dealing with new people, she occasionally likes to feign absent-minded cluelessness instead, as she finds it amusing to be taken vulnerable and naïve as to give her victims a false sense of relief or misunderstanding.

Cas has two major weaknesses: curiosity and self-indulgence. She likes to know things, and can become cross if she thinks people are deliberately hiding information from her when they don't need to. She also likes eating desserts, especially chocolate. While she loves collecting money, it's something of a hobby rather than a compulsion, and she parts with it easily when it's needed for the sake of satisfying her other enjoyments. Which is killing and torturing.
