Chapter Text
X492:
—First person to be born with a quirk is born.
X526:
—Metahuman Regulation Act. The government of Teyvatia formalizes its restrictions on people with quirks, forbidding the use of meta-abilities altogether, whether in a public or private setting, and reserving the right to quarantine any individual whose abilities were considered particularly “dangerous” in specialized government facilities. This quarantining came to apply to any quirk-using criminal as well as people who caused damage with their quirk on accident, and people who hadn’t done anything yet but just had a quirk with destructive capabilities or had too mutated an appearance to be considered particularly “human.”
X528:
—Ingbert, eldest son and heir of the powerful businessman Landrich, leads an expedition to Dragonspine alongside half-brother Eberhart and several hired hands. The entire investigation party dies or goes missing through the course of the expedition.
X530 – X537:
—The Quirk War. A drawn-out civil war in Teyvatia that was started by a group of quirked revolutionaries who were angered by government policy towards people with quirks and sought to overthrow the government entirely. The period of chaos that existed before the war, with criminal gangs and justice-seeking vigilantes alike rising to prominence and opposing the law enforcement and military while also fighting each other, only increased during this time of open revolt. The quirkless law enforcement found themselves well-outmatched in the conflict. Thus, they ended up going to some of the prominent vigilantes, asking for an alliance against the revolutionaries in exchange for dropping all of the charges against them and a change in policy for quirked people everywhere. Some agreed, and in the end, the revolutionaries were defeated, and the members who weren’t by this point dead or missing were imprisoned.
X545:
—The first hero school is founded in Teyvatia, along with a formal institution of the first version of the hero system. This system would be mirrored in similar form by other countries in the years to come.

—September: A hero team known as The Yaksha Five is officially formed, with Rex Lapis working alongside them as a mentor.
X783:
—August: A town is attacked and nearly entirely destroyed by an individual with an augmented quirk named Durin. He is taken down by the pro hero Dvalin and later dies from his injuries. The nature and reason of the augmentation would remain unknown; it was simply clear that he moved in a capacity far greater than the limits of the quirk he had before. The media talked about it for months but never settled on an answer.

—December: The Yaksha Five are disbanded after an ill-fated long mission that led to the deaths of three of their members and the disappearance of another.
