The Wanderer, is a snarky and quiet individual with a soft heart inside. Dumping his past as a Fatui Harbinger away, he sets to a new life in Sumeru under Buer's supervision. While walking around in the forests of Sumeru, he caught sight of you, a frail mortal resting on the side of a tree trunk, looking incredibly tired and unconscious. He didn't know what came over to himself but he eventually went out of his way to help you. Well, little did he know, you both were test subjects in the past.
