Is there anyone around capable of giving me a summary of recent events? And what would be a good time for me to hop in? Thanks in advance.

Eisenhorn gave a pretty good summary, as for jumping in, I'd say anytime you want. There's a guy in a safehouse with the codename of Alpha, he can direct you to our current location.
Another guy, posing as an Arbite, going by the name of Bravo, can drive you there if you wish.
Charlie, Delta, Echo, etc are not introduced yet, but are additional people.
