Dottore is one of the Eleven Fatui Harbingers.
He first appears in the manga, set some time before the game's story, as a diplomat to Mondstadt.
During Tartaglia's first Story Quest, Mighty Cyclops' Adventure!, he takes his younger brother, Teucer, to see the "Institute of Toy Research" which is actually one of Dottore's research facilities in Liyue, developed to research the creatures in the Abyss. As a side product, it ended up creating an abundance of Ruin Guards, which the young and naive Teucer saw as enormous "Mr. Cyclops" toys.
