Rover travels across Rinascita, eliminating all of the Nightmare Tacet Discords. The Ivory Gatekeeper contacts Rover again.

Strange White Cat: “I see... so that's what was lurking deep within the network of Dreamscape Nodes. There's something actively collecting people's nightmares and negative emotions... Well done, Rover. I can feel that all the Dreamscape Nodes are now connected. The hidden threats have been cleared… I’ve prepared your rewards, meow. Let’s discuss the details in person.”

Though they resemble foes already encountered, they bear a new, twisted energy from corrupted dreams..

Rover returns to the Ivory Gatekeeper.

Strange White Cat: "Rover, do you think that special TD is similar to some of the memory fragments in the Somnoire?"

Rover: “There are some resemblances. And it reminded me of an old acquaintance...”

Strange White Cat: "I'm talking about the corrupted dreams, meow. Dreams are visions from the subconscious. Even when they solidify into memory fragments, they still carry all the joy and sorrow of the dreamer. But those special TDs... it's as though people's subconscious have been unified by a single concept, carrying nothing but one desire. I tried to peer into the depths of the network to see what lay beyond. For a brief moment, I saw a single frame of image and almost drowned in the tidal sound, losing myself.

Rover: “What kind of image?”

Strange White Cat: "I saw a pitch-black abyss, where people were neatly lined up, crawling, performing the same gestures, murmuring the same words, trapped in the same dream. In the next moment, they noticed my presence and turned to meet my gaze... Their eyes... Their pupils were stained with the same substance... And in the darkness behind them, a pair of enormous eyes slowly opened... I've never seen a dream like this before."

Rover: “That sounds unsettling... They all turned to look at you?”

Strange White Cat: "Yes. Just thinking about it gives me an uneasy feeling. That dream was far too dangerous and unsettling. What could be lurking in the darkness beneath Rinascita's waters? Have the people of Ragunna always been living with such a threat? So, Rover, I'd like to ask you to keep eliminating those TDs hidden within the network. Only then will the dreams housed in the Somnoire be safe.

After completing the Quest of Faith and finding all the Journal Pages:

Strange White Cat: “Rover, I can feel the sea fog over this island thinning. Although it's still not stable, the Dreamscape Nodes here should be accessible now, meow.”

After completing the Where Wind Returns to the Celestial Realm, Rover can access another Dreamscape Node.
