Need quick update guide to Hellboy & the B.P.R.D. universe (SPOILERS)

I’ve been following the story up until recently when Hellboy fought he witch, died and went to Hell.

There are several concurrent titles in the Hellboy universe and I have not been able to follow them all. What I’m a little unclear on is what the status of the earth is. Is the entire earth under attack and few survivors are left or is the majority of civilization intact?

I have many Hellboy/BPRD questions as well.

Is Baba Yaga still around?

Has Rasputin managed to defragment his soul and come back?

I’ve read Hellboy was revealed as rightful heir to Arthur Pendragon. I’d like a lot more details on that.
