・ With Silver Wolf's help, Firefly infiltrated Penacony's dreamscape through the Primordial Memory Zone.
・ According to Silver Wolf, The Family has an omniscient presence within Penacony, though its true identity remains unknown.
・ In the chaotic Memory Zone, Firefly discovered memoria left by another Glamoth Knight, designated AR-214, a companion with whom Firefly once shared cherished memories.

・ After welcoming you into the dreamscape, Robin investigated the "dissonance" within and discovered its source was Firefly, who at the time was considered a stowaway, being hunted by the Bloodhound Family.
・ Through "tuning," Robin monitored Firefly for a period of time to verify her identity.
・ After discovering Firefly's remote communication with Silver Wolf, Robin confirmed her identity was far from ordinary and continued the chase, following her to Dream's Edge.
・ At Dream's Edge, Robin encountered Sparkle disguised as Sunday. After probing verbally, Robin, unable to suppress Sparkle due to an abnormal surge in the power of the Harmony, was "killed" by her.

・ After encountering Memory Zone Meme "Death" and getting separated from the Trailblazer, Firefly didn't return to reality, but instead met a collaborator of the Stellaron Hunters, a Cremator named Constance "The Dahlia."
・ According to Constance, this dreamscape concealed a crime committed by the Dreammaster, which could help the Stellaron Hunters understand the secrets of the dreamscape.
・ With The Dahlia's help, Firefly discovered the truth of the crime: the wreckage of AR-214's armor wasn't made of memoria. This indicated she had been here in person, though the reason for her demise remained unclear.
・ During this time, Firefly revealed the source of Glamoth Knights' power. Each knight was a Pathstrider of the Propagation.
・ Firefly decided to continue investigating, but encountered you traveling with Acheron and Black Swan. Upon learning of Acheron's identity as the Emanator of Nihility, Firefly remembered her "Zero-Point Mission."
・ As it turned out, Firefly was one of the "Special Four" among the Stellaron Hunters, tasked with single-handedly averting the apocalypse, and she was also responsible for keeping you untainted by the Nihility.
・ To this end, Firefly took a shortcut and reached Memory Zone Meme "Death" ahead of you, sacrificing her "First Death" to prevent Acheron from drawing her blade before you.
・ Firefly thus arrived at the Dreamflux Reef, but to ensure your safety, she returned to you with The Dahlia's help, appearing as "SAM" to force Acheron to part ways with you.
・ Afterward, The Dahlia found Black Swan in Acheron's room. The two turned out to be old acquaintances with bad blood, and in Black Swan's eyes, The Dahlia was absolutely dangerous.

Mission The Moment Before My DeathIcon Trailblaze Mission Small BlackThe Moment Before My Death

・ After being killed by Sparkle, Robin arrived at Dreamflux Reef and, with Mika's help, got acquainted with the surroundings.
・ When she decided to gather information about the outside world, Firefly and The Dahlia found Robin and invited her to the Stellaron Hunters' secret base.
・ Firefly revealed her true purpose to Robin: she suspected the Dreammaster was plotting a conspiracy that endangered the dreamscape. Considering the disharmony within the dreamscape, the two sides formed a temporary alliance.
・ The Dahlia showed a piece of history salvaged from the Memory Zone: AR-214 was harmed by the Dreammaster himself, who claimed it was to create a paradise through Propagation.
・ Just as they were about to continue their investigation, Black Swan arrived, sent by Sunday to find Robin.
・ Black Swan revealed The Dahlia's true identity: she wasn't a Stellaron Hunter, but rather the Dreammaster's collaborator. In the dreamscape, she had been using the Memokeepers' abilities to disguise herself as an ally of various factions.
・ Before Firefly could react, The Dahlia teleported her away, while Robin managed to escape under Black Swan's cover. However, The Dahlia had already planted The Cremators' flame in her consciousness, making her forget this recent experience.
・ Black Swan confronted The Dahlia, but the Dreammaster shared his power with The Dahlia through "Divine Law," making her far more powerful than before while in Penacony. In desperation, Black Swan also used The Cremators' technique to burn away the "Divine Law" on The Dahlia.
・ The Dahlia led Black Swan to a strange dreamscape called the "Dream of Gnawing Oak." As it turned out, based on their observations, the two had already reached an unspoken understanding, and their previous confrontation was actually The Dahlia's ploy to burn away the Divine Law, through which the Dreammaster had not only shared power but also placed a containment mechanism on The Dahlia.
・ Here, The Dahlia revealed the Dreammaster's conspiracy: He had no physical form, and not long ago, he completely killed his own consciousness, transforming into four functionally distinct "Divine Laws" to accomplish his ultimate plan, to recreate the Swarm Disaster within Dreamjoy.

Mission Omen in the TreesIcon Trailblaze Mission Small BlackOmen in the Trees

・ While the Express Crew was witnessing Mikhail's life story, Firefly, not being a pathstrider of Trailblaze, couldn't accompany them.
・ Sparkle, as an ally of the Stellaron Hunters, arrived here to deliver intel about the Dream of Gnawing Oak.
・ Firefly continued to journey with the Express Crew, earning the title of Festive Superstar together during the Moment of Scorchsand.

Every Dawn of the World

Mission Every Dawn of the World StelleIcon Trailblaze Mission Small BlackEvery Dawn of the World

・ After being drawn into Ena's Dream by Sunday, you awakened with Black Swan's help and reunited with your companions.
・ Black Swan revealed to you the three-phase nature of Ena's Dream, and everyone decided to work together to break it.
・ Acheron would deliver a strike, working with Boothill to shatter Sunday's beautiful illusion.
・ Firefly confronted the core of the Swarm Disaster, "Harbinger of Death: Swarm Nightmare." After victory, she claimed the Stellaron to temporarily gain control over the Swarm Disaster, using it to tear a fissure in the Primordial Dreamscape, though this led to her second death.
・ Within the Twelve Hours, Sparkle detonated all of Penacony, allowing everyone to cross the dreamscape and face Sunday directly. Meanwhile, Robin independently orchestrated the Charmony Festival, protecting every dreamer from the blast.
・ Jade released her Cornerstone, gathering power from within the dreamscape to force Sunday, who had nearly become an Aeon, to descend to an Emanator.
・ Finally, you and the Express Crew faced Sunday once again, and emerge victorious.

That Which Shall Be

Mission That Which Shall Be StelleIcon Trailblaze Mission Small BlackThat Which Shall Be
