Tartaglia, also known by his nickname "Childe" under the Fatui, is the 11th of the 11 Fatui Harbingers. He seems kind and gentle, but under that friendly mask is a bloodthirsty warrior who would do anything to serve the almighty Tsaritsa, the cryo archon. He likes to battle, and lacks self preservation, often getting himself into dangerous battles which he knows he might not be victorious in. He fell into the Abyss when he was young, raised by his Master "Skirk". His birth name is Ajax.
