So, now that the special manga for Kurapika's past has been released, along with the movie Phantom Rouge, we know how the Kurta actually died - but what steps were taken to get there? What happened?
We saw the picture of the Phantom Troupe five years prior to the Yorknew arc, showing them just about to head off to the massacre as indicated by the knife in the map and Omakage being present. It was a strange picture, particularilly the part where Shalnark was wearing clothes almost identical to that of the Kurta clan.
So, what was there plan? How did they learn so much about the Kurta clan?
An inside person?
The Hunter website (is Shal had it back then)?
Not to mention the message that they left, stating "We accept anything, so take nothing from us."
Is there something the clan took from them?
I've always thought it was tied into Sheila somehow, either intentionally (she was working or hired by the troupe) or unintentionally (they were spying on her and happened to witness her interactions with Kurapika and Pairo).
As for Shalnark being a Kurta--I'm still unsure about this. He has the clothing style, but I'm not sure if he's an actual Kurta.
