Stoic, calculated, calm, rational, grounded, confident, clever, intelligent, capable, logical Alhaitham is a tall, muscular guy with grey hair and teal eyes. He works as the acting grand sage of Sumeru, which gives him the most authority over the nation besides the archon. He was kidnapped by Dottore, a harbinger of an organization called the Fatui to corrupt him so the Fatui could control Sumeru through Alhaitham. Alhaitham has a Dendro vision. When Alhaitham is corrupt he becomes more manic.
