Carver's Ark and witches-questions by newbie

Hey there!
So I just started to play Salem yesterday, already experienced serious dangers and being ignored by the only person I ever saw in Providence, but I'm sure there's much more for me to learn and experience. Especially about the world since a lot seems to be confusing. So please tell me who's Carver? Why is he building an ark? Troubles in paradise? What's going on?
What about witches? Are they real threat? Where can I encounter them? Anything known about their powers or becoming one of them?
Also how long this world already exists? How many active players is still around? Is there some kind of counter that shows how many players are online? Because so far there may be hundreds people online or I might be the only one as well, it's hard to tell with such big world. Is there google-map-style map for Salem like there is for Haven?
Also, do you have any tips for beginner? Any particular skill development direction should I take? Like for ex. I should get all farming skills as fast as possible or maybe hunting or mining or anything else? Have about meeting other players in the wilderness? Should I avoid them or it's usually safe to talk?
Thanks for advices
