User blog comment:Hawkinz340/Who is Zzigg Zoldyck and who is Don Freeccs?/@comment-25032153-20140623100037

They have said in the manga that their are human type natives that act as guides for the uncharted trips so the Don could be one of those people and be welcomed in the Hunters organisation as most of the trips have had a hunters and guides working together so if you think about that the Dark Continent could also have a Hunter organisation within it that are controling the desarters and how they effect the inner world. they also allow select people to start a family in the inner world after they have acted as guides and they have all ate the Nitro Grain which is similar to the Nitro of Toriko which have survived like the immortal desease and Zzigg was a friend of his that didn't want to take over the family trade and was cut from the family as they had already had the heir so he could do the trip because he had all the requirements and did the hunter exam with former chairmen and choose to stay in the dark contentant because it was fun and traveled with Don as a Pacted for information that he was writing.
