Connecting Factions with Prophesies

My husand just got FACTIONS (collectors Edition! the rat! ) Anyway, how do you get from Tyria (Ascalon) to Cantha?? Is there a quest that sends you on your way and if so where does it start??
And the same with the others. . how does one get form Cantha to Ascalon (providing they have Prophesies) and how will we all get to the new (zones) in NIGHTFALL when it comes out?

*I know. . more newbie questions. . .so what?

Providing you have added the key to the same account as your Prophecies key:

To get a Tyrian to Cantha, see Firstwatch Sergio in Lion's Arch. He has a quest to meet Mhenlo outside.
To get a Canthan to Tyria, talk to Guardsman Chienpo in Kaineng Centre

Ok. .thanks. .
