Question about Pariston's involvement in BW1 from chapter 359 and 346
Hi all, after years knowing just bits from the anime version, last month I finally decided to purchase the volumes of the HxH manga, awesome read so far!
Just finished volume 34 (no spoiler, please) and I have a little question about Kurapika's words from the sixth panel of the first posted page from ch. 358. I don't understand at all what he means saying that thse Hunters guarda unaware of the succession war were sent here from Pariston. My logical assumption is that Kurapika is talking about the Trump Hunters/Kyousen that Pariston attempted to infiltrate through the Hunter Exam but that were discovered and rejected (see the third panel from the second posted page from chapter 346). Am I right or I misunderstood and there is another explanation?
Also, another question from the same Pariston's line from chapter 346: why Trump Hunters attempted to make the last Hunter Exam if they are already official licensed Hunters? I know that the 289th Hunter exam was made exclusively for recruiting provisional Hunters for the Dark Continent Voyage, but I don't think that people with already a licence had to pass it. Am I misunderstanding something?
