He's from Morepesok, Snezhnaya. He's also the youngest Fatui Harbinger! (In his mid to late 20s) -He as at least 2 older sisters and he has 2 older brothers. He has three younger siblings, Teucer, Tonia, and Anton. Teucer is still a kid while Tonia and Anton are teens. Tonia is older than Anton. -Ajax ran away from home at the age of 14 because he was bored of his domestic life. He ended up falling into the abyss, where he was surrounded by dangerous creatures. He met his master, Skirk, there. She taught him how to survive. He stayed in the abyss for 3 months, although in Teyvat, it had only been 3 days. -He woke up in the middle of the forest three days after running away, being found by his mother and older sisters. With all that training under Skirk, he became bloodthirsty and violent, causing many fights in Morepesok. His parents decided to send him off to the Fatui to discipline him, not knowing he'd end up serving under the Tsaritsa directly as a Harbinger. He also became obsessed with world domination. -His occupation as a Fatui Harbinger is known among the older members of his family. Everyone knows except Teucer, who believes he's just a toy salesman. The best in all of Teyvat! Ajax doesn't want Teucer to know so he can stay innocent. -Despite being all bloodthirsty and obsessed with world domination, he's really a good guy. He's the closest to being normal among the other Harbingers. -He's one of the first Fatui Harbingers that Lumine has met and the first one for her to befriend. He regards Lumine as his comrade, sparring partner, close friend... He writes about her in the letters he writes home to his yonger siblings whenever he's out for a mission. Being very descriptive. -Teucer already knows Lumine from the time he ran away to Liyue just to see his older brother, Ajax. Lumine took care of Teucer and helped Ajax hide his true occupation from him. -Tonia and Lumine recently met in Snezhnaya... (To be continued!) -He had always wanted Lumine to meet his family in Morepesok!!!
