The first instructor from the academy isn't going to make a surprise appearance and die will be? My guess would be Aetherion's brother, since he already lost the rest of his family and would totally transform him into an ass-kicking emo with daddy issues
An odd speculation who will die, cont.
After a few heads are politely knocked together, the dark eldar will counter strike and and mercilessly slaughter the Dark Angels and take their ships, and start joy riding on them to random imperial planets.
Game of tthrones: everyone is mortal.
My guessing about who will die. It can't be Kor'la, Sha'shiva or Skraat, because they are very main characters, people love them and the comic is mostly about them.
It also can't be Johnson: first, he is too badass to have his last fight described in less than 5 pages; second, he is also one of the main characters; and third, in the 200-th Night Show he said that there is something aboyt his skin colour change that he can't say yet.
Durchii kid obviously has a plot purpose, so he will not die.
And in the result only eldar are left in the main character list. Keraiel is vital for the Eryon, so Aetherion has the weakest plot armor so far. But it also can be any of the secondary characters.
