I assume Nin’janjin was killed when the Inchoroi were wiped out?

That's a reasonable assumption. But  it's never explicitly called out bothers. He basically just disappears after striking down Cu'Jara Cinmoi, the most renowned Nonmen King in history. If Nin was killed, I'd expect it to be mentioned somewhere.

I've got no proof, but I'd bet a lot of money that we see Nin again.  I don't think a character like would just die off screen in that fashion.
