i just remembered the super deep headcanon lore i made for krux & acronix's family lol
before the time twins were born, the previous elemental masters of time (including cittrix) would have a handful of villages under their personal protection
it started out as a noble thing but it VERY quickly turned into greed since the time family would prioritize the safety of the villages who gave a lot of "offerings" (like land, gold, property, etc) and would straight up abandon villages that didnt give "offerings"
next, their father, who was named kaius, was the ruler of a small kingdom that was constantly at war with other kingdoms
kaius ruled his kingdom with an iron fist and hed immediately crush any rebellions or coups that would form. he was also fighting off his own family since they were all trying to steal the throne from him
krux was raised to inherit their father's kingdom while acronix was raised to inherit their mother's village protectorate but during the serpentine war they were like "nah. we're gonna do our own thing" and they made their plan for the revolt & world domination
they both really dont vibe with "birthright" stuff and theyd much rather put in the work to become rulers. also why rule over a couple of villages and a small kingdom when you can instead rule over the entirety of ninjago?
so yea krux & acronix are reverse (??) nepo babies LMAO
bonus: kaius is metalonian and since metalonia is seemingly more accepting of non-humans, krux & acronix are a lot more tolerant of serpentine & other non-humans compared to other ninjagans
