Travel to the Heroes' Plain and locate the entrance of the base (looks like a crypt), there you can meet 5th Talon Ordon Thrulmur inside. You have to talk to him and he will explain you what awaits you behind those portals.
Before you enter a portal it might be helpful to get either necro-levi or parachute, by dismounting any flying mount while in the air.
Note: You can enter any portal, but the fighting behind the portal in the north seems to be much easier. Also it seems that the portals are bugged, it might happen that not all members of your group will be teleported, so be ready to use evac. The bug seems to occur if any pet is summoned, so release all pets before you activate the portal.
