BACKSTORY. β
ajax knew who he was from the very start. a hero, a fighter, a winner. but for him, he had the unfortunate luck to be born into a small fisherman village in the outskirts of snezhnaya. nobody even knew how to wield a blade, much less fight. he yearned for a greater purpose. one day, when he was 14, ajax decided to go travel the world. of course, he had no clue what he was getting himself into, and ended up falling into the abyss. he surely would've died if it weren't for his encounter with a woman named skirk, who eventually began to teach him her ways. he didn't know why exactly she took him in, but she did. and he was rapidly learning her ways of combat. ajax was stuck in the abyss for three months, training with a woman who didn't even speak to him. that three months was only three days in teyvat. when he returned from the abyss, he was surely not the same. of course, on the outside he was still polite and kind, but deep below. there was a urge to fight, to create bloodshed, the adrenaline he received when in battle, it was like nothing else. it kept him sane, oddly enough.
eventually, his parents caught on that their ajax wasn't the same. maybe it was the lack of light from his eyes, or the ruthlessness in his violent actions, or just the pure thirst for blood, but something in their son changed. ultimately, they decided to send him to the fatui after his constant chaos in an attempt to humble him. but it was ultimately the opposite. there, he easily overpowered opponents, incredible for a fourteen year old boy. he was spotted by the fifth harbinger, pulcinella. the rooster saw much potential in the boy, deciding to take him under his wing and taught him the ways of diplomacy. ajax never stopped getting stronger either, training after training. to the point where he took control of the eleventh harbinger spot. stealing the name tartaglia and the childe from it's predecessor. alongside the insignia of a harbinger, he was gifted an electro delusion for his very much well done work.
ajax doesn't wield a bow because he particularly finds it cool or badass. but because the weapon of the bow is his weakest element, any professional archer could take a look at his form and cringe internally. he simply isn't thinking properly, like the regal and formal way of a marksman. which is also the reason he frequently uses his hydro vision to create weapons of hydro, like a spear or dual blades. childe frequently uses the bow, despite his lack of skill hindering his abilities and giving him a disadvantage.
