MMORPG.com: What levels is this expansion targeted towards. From where / how will the new zones be accessed?

Travis McGeathy: The expansion zones start at around level 50 and work their way up from there. With the revamp of Freeport and the Desert of Ro, we've also added additional expansion-only missions that take place within those zones that cater to lower level players. In addition, we've created more than a dozen new monster missions that are available to players of all levels including, for the first time, a monster mission raid.

The expansion is broken down into four main areas, the Plane of Magic, the Plane of Conflict, Takish Hiz, and the Theater of Blood. Access to each of these comes from different areas within Freeport and the Desert of Ro. The exception is Theater of Blood. Gaining access to that zone is a secret that players will have to uncover on their own.
