"Dottore's unfettered research towards creating a god, or elevating humans to the level of gods, left him ostracized from mainstream society but paved the way for him to become the Second of the Eleven Fatui Harbingers, with strength comparable to the gods'. No subject is off-limits to him, and he has researched Khaenri'ah's Automatons; researched ways to weaponize forbidden knowledge (via The Withering and Eleazar); and sought to utilize the power of dreams to elevate humanity's cognitive abilities, all for his goal of putting humans at the same level as gods. This ambition is likely the reason why Pantalone, who seeks to "overthrow the natural imbalance between gods and humans," works closely with Dottore." -Genshin Impact Wiki
