Re: Magellan
now that you mention it, remeber the slave price list for the human auction?
there was one race that we don't know anything at all, maybe its like the sky island but in in a hell-ish vercion, and thats where they came from

Minkmen perhaps? Sounds like people with fur to me (like a Mink Coat).
On Magellan, to me he is probably the first villain since Crocodile that needs to be defeated, but I cannot guess how he will be defeated in the end. I mean, Enel, Lucchi and Moria were always going to be defeated by Luffy, and Kuma and Aokoji were always going to defeat Luffy in the arcs they appeared. In this one, like Crocodile, Luffy has lost but has not escaped to relative safety. I feel people can guess how Ace or Jimbei can beat Magellan, but if Luffy doesn't defeat him in this arc I'll feel disappointed.
To me, my main wonder about Magellan is whether he will outlast this arc. Most villains thus far have had the potential to be influential to the Strawhat's travel in the future, though most haven't, all villains have been forced to leave the place Luffy met them meaning they may meet again one day, even if it seems unlikely. On the other hand here, Magellan will doubtfully leave and threaten Luffy further on, so he may possibly be the first villain we can 100% close out of being influential later.
That said, I can already see the Hannybal, Magellan and Sadie Cover Arc, and in my mind it's hilarious.
