Banshee mixes with a Spirit of Vengeance but this spirit is not trying to seek revenge so he is a Spirit of Variance (I know, sounds so dumb but it worked... in an odd way) and when said spirit takes over Banshee's body, much like a Spirit of Vengeance becomes Ghost Rider, this one goes by the name Vox Ignis, the Voice of Fire! That is cool

I finally understand that the Alter is in Legion's head, accessed by Krakoa gates and that it is adjacent to the Astral Plane... it shows up as a beach beside the Alter
Found out that, according to writer Si Spurrier here, that
EVERY human has an X-gene

(apparently?) and when the new Black Knight, a daughter of Dane Whitman, comes in contact with a human, she activates that X gene for one hour. Mostly stupid powers, like becoming invisible, but only from the waist up

No idea if this humans have the x thing is going to be picked up by other writers as this... this is kind of a big deal and it is coming from an ancillary X-Book and not the main so... yeah, we will see... or not

Also, the book seems to be leading us to believe that this new Black Night is also responsible for Nightcrawlers new horns as when she took Angel's hand he became a huge bird-like creature. One of the X people gave the power a name, but I forgot.

Oh yeah, on the last page we are shown the woman that raised Nightcrawler, Margali... so I have discovered!! I had to look her up... I was so scared to see spoilers, but I made it. She has a big history that I do not know and did not check on (for fear of those same spoilers) so if anyone can tell me about her, without spoiling too much, I would appreciate it.
