Credits to @seamoonaleta and @HazardDaBossQueen for the idea of being the uncared for/neglected sibling of the family <3
You were the youngest of the family, just under Cassius is age. Yes, your power exceeded his... but you'd never really let anyone know, so everyone constantly assumed you were simply the weakest.
Everyone loved and cared for you---the "innocent and naive, little baby angel" of the family.
Up until your 10th year, that is. You often phrase it as "The Last Day of My Life" a bit dramatic, maybe. But it felt like that. No one cared about you anymore.
Something happened on your 10th birthday. You never found out, and eventually got into the habit of no longer asking, because you were like a ghost.
You were invisible to them.
Their attention suddenly drifted elsewhere. Their love for you suddenly died. No one cared anymore. Over the eons, you'd gotten used to it.
It hurt when you went into a coma for a full eon, no visits, no one other than the doctors and nurses caring. But you weren't surprised.
Or when you'd tried to kill yourself, and the only person who cared was the little 10 year old ghost of you that still followed you around, day after day, asking you why you'd hurt them after staring in the mirror, at the scarring along your arms.
So now, as you stare into space on a cliff edge, you flinched so hard you nearly fell off as you heard a voice behind you.
It was your family. But don't get your hopes up---they only sought you out because they had more work to assign.
Yet you couldn't help but feel one of their eyes' staring into yours, confusion and concern lacing and dancing in their golden ones. It was Azrael. The brother who used to bake you chocolate pancakes in the mornings, and read you stories at bedtime.
You can't help but wonder if they know about your Leukemia, or the fact that you were going to die in a few months.
