Diamáchi Plots
Natalia is not Diamáchi-born but has adopted the last name as a way to symbolic abandon her place as the next in line for the Tsar throne. She responds equally to both Natalia and Caecia, though the Diamáchi are likely the only ones to know of her by both names, every stranger she meets finding the name Caecia rather than her personal name. She is fluent in Russian and it is her primary language, however she can and will speak the English she knows. She is not completely fluent in English, but it's close enough - a few grammar mistakes at most. She is a fan of observation and will likely remain silent unless spoken to, as she had been trained to do by her parents.
She is a huntress. She found the Diamáchi on accident while on the run from her horror of a fiance and her parents, and she quickly joined them because she simply wanted to stop running, but she loved the idea of constantly moving. She fit in and mainly does hunting, catching as much as she can so she can personally make sure everyone has food even if they already hunt for themselves. She is guarded and has walls, but those closest to her will be able to break down those walls and actively get to know her.
Natalia does have a bit of an alter ego or personality that sometimes makes an appearance when she is fighting to defend something that she loves, or someone for that matter, and their name is Kaskad, the name given to her by an instructor per tradition when she was a pup. The instructor noted her fiery defense and noted a shift in her personality whenever situations such as that arose.
