Why does the khyaak care

Why does the khyaak care so much? Why's he mentoring a semi-competent unwilling Haka when he could have achieved his goals much quicker if he did it himself? Even if his aim is to spread badness, why not choose someone more capable? What does he hope to gain out of this? Are the victims themselves important it is it the journey that's valuable? What are the limits of his ability, how much of it is bluster and how much is real?

Does the khyaak believe in a moral world, aka see the world in terms of good and evil, or does he consider himself just an actor who has to do things because he has to. How much agency does he have anyway, in the big scheme of things, is he a pawn himself or is he a puppeteer. And to what end? What does he hope to gain by these seemingly random acts of violence? Does he have personal ambitions here, or is this strictly business?

What's the khyaaks relationship to the white khyaak and the khyaaks of yore? How does he survive despite the brightness of the modern city? Where does he live and is he considering changing his living situation?
