Core Professions and Non-Core Professions

This'll be a very simple question. I am an owner of both Guild Wars: Prophecies and Guild Wars: Factions. Thus I have access to all 8 professions... When I buy Guild Wars: Nightfall (Chapter 3) Will I be able to create a Ritualist or Assassin in that chapter's campaign?

Ritualists and Assassins are Factions only, so no, you can't start an A or Rt in Ch3.

They can move from Cantha to CH3 area just like they can move from Ch2 to Ch1 tho.

Chapter 3 ?? can someone link me where I get that plz ?
