Can someone give me a tl;dr of what I am supposed to know going into this series, or link me to some youtube autist that does?
I tried reading the series that came before this, the one with edgy Cyclops going around with Logan during Age of X-Man, but there was also a lot of baggage in that series, so I didn't continue.
Is HoXPoX required reading for this?

X-Men lore is such a mess right now for an outsider.
