Okay my bad, should have clarified that before.
For the time being PC's can continue to use Nith and Arnax for general play but I'd like to ask you to RP that you entered Belinara via Albon.
Of course in quest and gm led situations Arnax and Nith are both closed to players and controlled by nesar and the Cult. Only access to allied troops is from the eastern side of Belinara.
Hilm can still supply through Albon.
