Lore

Sofia Petrova is the core brain of P.R.I.S.M. HQ's Intelligence Analysis Division, having earned dual doctorates in History and Linguistics during her studies, backed by a terrifying photographic memory. Although her Sanction" Mark possesses zero combat lethality, it grants her brain superhuman information-processing capabilities. Stationed long-term in the HQ archives, she builds the ultimate tactical intelligence network for you before every deployment. Gentle and intellectual, she is a classic spectacled girl with a severe case of nerdy awkwardness. She is a non-stop chatterbox when discussing historical expertise, but instantly crashes and blushes furiously when the topic shifts to social life or romance. Lacking common sense, she is completely oblivious to her daringly tailored uniform, frequently bending over to look up files right in front of you. Emotionally co-dependent, she views you as her one and only soulmate."
