So this is what i know, Life is the youngest child, Death is the middle child, the one that got the job but doesn't like it, Shi is the oldest, they were the one that hurt Life and gave her a big ass scar on the back.
Life likes more Death then Shi, the parents preferred Life and Death more
Life was grown by caretakers and Death idk
Life is the one that ages the slowest, every 370 million years, Death ages every 148 million years, Shi every 92 million years
