Avdotya Razorpen is the only non-Durin citizen of Zeruertza (being a Lupo), acting as the subterranean city's literature representative responsible for handling much of Zeruertza's advertisements and copywriting works. It is later revealed that she is Avdotya Nikolayevna Ivanova, the daughter of an Ursine noble and a lesser-known novelist. After her family was executed as a result of a political conspiracy, Avdotya is the only survivor from the purge and escaped from Ursus to avoid capture, and stumbled into Zeruertza by accident along the way. Astonished by the Durins' peace and lack of conflict, Avdotya became a naturalized, honorary citizen of Zeruertza, and has since been spending her life in tranquil. Due to her harsh past, Avdotya distrusts, if not outright shunning, anyone and anything from the surface world, and shows care towards the Durins and Zeruertza as a whole whom she believes to be a perfect "utopia".

After Gavial and her friends visited Zeruertza, and a shocking revelation that the city was in danger of being overrun by Originium veins, Avdotya at first opposes Gavial's suggestion to have the Zeruertzans migrate to Acahualla as she considered it to be unpleasant for the Durins, pointing out potential threats by the Sargonian Padishahs and Lords Ameer. However, she changed her mind out of the fact that she is not even a Durin herself and for her sincere love upon them, and managed to convince the Zeruertzans to leave. Following the exodus, Avdotya was taken under Rhodes Island's wing. Getting back to R.I landship, you took a train from around Zeruertza with Pozëmka, now that she became your Operator.

— Doctor, I'd like to talk with you of beauty and virtue, of those things I consider vanished from the surface. I've witnessed their existence aboard Rhodes Island, and you've told me that more of their sparks are alight upon this land still... I don't dare trust. I have to go and see it for myself.
