My party has returned to Neverwinter from the forest and ended the siege. Now they're wandering around the world with NPC Greywolf in the party but nothing new is triggered. Where should I go to progress the story ?

EDIT: Found it out, had to talk to a woman in Neverwinter to progress.

I've managed to win the game.

Does anyone know what to do with the ghostly figure in the Neverwinter Inn or with the hidden portals in the Cellars of the Mask in Neverwinter (my party members always said we could use them later) ?
