[Spoilers for HoC upto Chapter 5]

So Admiral Nok narrates to Tavore as to who the former Emperor started out with. They were Dujek, Duiker, Urko, Crust, Tayschrenn, Hawl, Surly, Toc the Elder and Nok himself. I need clarification on who the blue skinned Napans are, because Tavore says only they abandoned the Empress whereas the wiki says that Nok and Duiker are Napans as well?? No further spoilers though, please.
