I'm needing suggestions for my current plot arc of my campaign. I want to PCs to end up in the Nightmare Lands, but I'm not sure how to get them there.
Currently the PCs are in Port-a-Lucine, Dementlieu investigating an assassins guild known as "The Lords of Death". The PCs discovered that the The Lords of Death are really a private army under a Dominic Belafonte. Dominic Belafonte is a fairly high level wizard and a member of the Fraternity of Shadows (the Ravenloft society, not this message board

The PCs teamed up with a priest of Ezra, Ft. Jean-Pierre D'Aginorne in the investigation. Ft. D'Aginorne had a daughter, Yvonne that was a prominent NPC in the game, as well as a potential love interest to one of the characters. In retaliation for meddling in his affairs, Belafonte sent a group of assassin to Ft. D'Aginorne's house. The PCs managed to fight them off, but Yvonne was killed by the assassins.
Because of Yvonne's tragic death, the party became victims of the Nightmare Court. The Ghost Dancer took advantage of the situation and filled the PCs with dreams of guilt. Every night the party has a dream where they see Yvonne still alive, but chained up. Just as they were about to save her, an assassin would appear to slay her. However, the PCs have recieved help battling the Nightmare Court from Reymond (taken from the Kargatane's Book of Shadows) a seemingly catatonic "lost-one" who is appears as a mighty warrior in dreamscapes. With Reymond's help the PCs have started to fight back in the dreamscapes.
Now where do I go from here? I want the PCs to end up in the Nightmare Lands and get involved with the Nightmare Court. However, I need to resolve to the loose plot ends with Dominic Belafonte and his Lords of Death. Any suggestions?
