Question about the history event quests and the main story *Spoiler alert*

So in the main story there's happening the civil war thingy, idk I didn't complete because I'm not lvl 60 yet so everyone dies instantly to the enemies, but in the main story I'm in the part were angel goes to rune academy and tries to blackmail the headmaster, but elio does the recruiting idea and stops there, but it seems like he wants to join angel, and I wanted to know if thoses event historys that we get are at the same time as the civil war or before And in the new elio history event shows that he knows who's his father and mother
