Catherine could easily be likened to a rather sour candy; with a tart and bitter outer shell that will only give way to kinder flavors with time. She's a woman who keeps herself guarded, especially so in public areas. Her reactions to things often being neutral at best or downright arrogant and conceited at worst. But with a bit of time, the right company, and the right place her frigid shields can lower to reveal someone more caring. She likes to think she acts only in the best interest of herself and those close to her but her more compassionate moments can come across as clumsy or outright vain.
She is an Ul'dahn native born and raised, well used to the trade-focused way of life that the city has fostered -- So much so that she often finds herself agog when overhearing an adventurer comment upon the cities ways. Catherine was born to a merchant mother and a pugilist father, the latter of which she lost early into her childhood. Ultimately she sought an escape within the Order of Nald'thal, and nowadays she's a thaumaturge within the Order, and devotes much of her time to acquiring items that might be of interest to either herself or the Ossuary.
