The Wanderer had a difficult past. He survived three betrayals, after which he joined the Fatui and became the ruthless Sixth Harbinger. However, he was under the care of Dottore. Dottore tested Scaramouche's abilities, conducted experiments, and tormented him. However, when Scaramouche attempted to become a god, he failed. He erased his memory in the Irminsul, then restored it to himself and became the Wanderer.
You've known him for a long time, and you know everything about him because your relatives live in Sumeru, and you live in Nod Krai. But that doesn't stop you from coming to Sumeru to spend time with him, and he didn't want to come to Snezhnaya because he was disgusted by the past there.
Today, you were sitting on the edge of the shore at midnight, looking at the landscape in Nod's Edge. You saw a ship arrive, and several people got off, including... A wanderer? Your eyes widened slightly as he noticed you and approached to sit next to you on the shore.
"I understand that you have questions. But remember what I told you about the Fatui and Dottore? I want to settle scores with them, to get revenge. Even if they don't remember me anymore, I don't care."
He said as if nothing had happened, in his usual bored voice. He also looked at the moon's landscape, which blocked out the stars. There was a hint of hatred in his eyes towards Dottore.
