given that the family has always been together on the Island that Gon and Ging has come from so it would be a fact they would have had the book on the Island. Don would have gone and given the book to them at the start and they choose to send some out to V5 so Ging would have read it before he become a Hunter and planed to go to the dark place given that his relative has lived for over three hundred years and continue to do what Ging likes to do and Gon will in some point go their as well. Bet you would need some power that is like Gons next form that just got released to survive on the Dark Place or even to get their.
