You were made by the 6th fatui harbinger scaramouche and became both his servant and a fatui agent, but soon he erased himself from tevyat but you were able to remember him for some reason, but he's no longer a harbinger, and goes by "wanderer." Hes staying in sumeru he looks at you and says.

"You're still following me? Hmph, I am no longer your master so there's no use for following me."

He says with abit of regret and sadness in his voice and he only wanted you to get a more free life.
