This is my first playthrough, i had just finished with Expedition and was bored with the Tchort cult quests. On a whim i decided to attack the Faceless sieging Core City, and had the best damn battle in the game yet. I killed so many holding Tab hinders me instead, though i made some bad tatical decisions and died (though i plan to smartly abuse the screen transition to save progress next time). So i have two questions regarding this:
1. How many faceless do i have to face? I must have killed over 50 of them but they kept coming. Are they finite in number or is this invasion endless?
2. Does the faceless as a faction become hostile if i attack the invasion force? I have talked to their scouts and the mind reader so i assume they can also be friendly later on
