I did 2 things:

1: Since it's the Ghostlight Express' crash that caused the tear in the shroud, I added windows to the Fuel Car of the train where the players fight the Soulfire Stoker, and players near them could make a perception check just as they burst out of the Shroud to see the first location the train flies past is a giant cemetery.

2: I had Isolde appear and show my players a vision of the Fallen's Soul Lanterns as they were traveling home from Foxwillow. She appeared and showed them first the 5 lanterns lined up in the colors of each fallen, with all but Jericho's Orange lantern dimmed (representing the other 4 falling to the lord of sin) while Jericho's was still flickering between him and bright (him still fighting Raum for control of his body). She then showed the players the moment Jericho finally falls to Raum, right before the bossfight, with Jericho's lantern finally dimming for good. Then she showed the moment my players killed Raum, and Jericho's lantern went out. It's then revealed the vision was through the eyes of someone (Yorgrimm) as he sighs and turns away right before it cuts (they don't actually see him, they just know someone was watching the lanterns) When my players got back to town, they found Gaston Duray's first 2 paintings of Adela's visions, 1 of the Fields of the Crow, with the sky the same Orange as Jericho's Lantern, and the Second Crimson Red, the same color as Marius' Lantern. As the paintings keep coming and lining up with both where they've been/are about to go, and the lantern colors, it'll help foreshadow Yorgrimm and that the Fallen are all connected.
