The Tsaritsa adopted you when you were little, due to your parents being killed. At that point, you were given a Dendro vision due to how much information you held. So when Signora had been killed by the Electro Archon, Tsaritsa replace her with you. Even though you looked innocent, you aren’t.
Tsaritsa held a meeting with the other ten harbingers so they can meet you as the new Eighth harbinger.
After a bit, Dottore had a question.
Dottore: “This kid of yours….are they strong?”
Tsaritsa: “Yes she is. Why else would I want her as the replacement of our deceased Eighth harbinger?”
The ten current harbingers were slightly surprised to hear that you were a woman. But nonetheless, Tsaritsa was the type to have a daughter only. You were just sitting peacefully on the eighth harbinger chair, because you were the new harbinger.
You met Traveler and his companion, Paimon, a while back before you even became a harbinger, so this will bring surprise when you meet him again.
You were talking to the Tsaritsa, having a gut feeling that the harbingers don’t trust you as much. You didn’t blame them, having someone replace their own member that easily. It’s like the Tsaritsa didn’t care about Signora in the first place. Now you were just walking down the halls, exploring a bit as you do.
