Following their escape from the Nightingale Bastion and their return to the burning streets of Dresden, the traveling party needed two things: a route to the Capitol Building and someone who knew the city's hidden infrastructure well enough to provide one. Barkevius Frumpymelon knew exactly where to start looking.

Before he had fled Dresden and the weight of his family name, Barkevius had known Coalborne as a small-time peddler working the edges of the warehouse district — the kind of man a merchant's son with something to prove found useful during his college years. What Barkevius found when he led the party back to those same streets was something considerably more than that. Coalborne had grown in his absence. The warehouse district now housed an expansive underground bazaar, a labyrinthine illicit marketplace operating openly beneath the noses of a Nightingale regime that had, it seemed, found the arrangement mutually convenient. Coalborne presided over it from the center of the operation, surrounded by lackeys and the quiet authority of a man who had made himself indispensable to the city's underclass while the revolution burned overhead.

Barkevius had not expected this. The transaction was conducted without warmth. Coalborne, in exchange for the kind of goodwill that men rebuilding a city might one day be positioned to repay, provided what the party needed: knowledge of the ancient sewer network running beneath the river and the means to access it. The surface streets were a kill-zone and everyone in the warehouse district knew it. The tunnels were the only viable route to the seat of power, and Coalborne's people knew those tunnels better than anyone.

With that intelligence secured, the party made their way to the ruins of the Cathedral of Amandine, reduced to a bombed-out husk by Nightingale artillery. There they met several revolutionary contacts who had been using the cathedral's wreckage as a gathering point: Reverend Isaiah Windlass, a priest of Amandine; Orliath, a professor at the local College of Arcane Studies; and Lavinia Overton, an undersecretary for the former Council of Merchants. The contacts confirmed what Coalborne had told them — the sewers were the only path — and provided what the kingpin had not: the political intelligence of what they would find on the other side. To reach the hidden entrance to the tunnel labyrinth, the group would first have to navigate the Tristessawood — a legendary, haunted forest on the outskirts of the city that remained under constant Nightingale surveillance, ostensibly to suppress illegal demon worship. Given what the party had uncovered at the Nightingale headquarters, serious suspicion arose about that mandate.

The transition into the Tristessawood was marked by an immediate, unnatural shift in reality. The sounds of the revolutionary fires and distant bombardment faded into a suffocating, heavy silence. As the party pushed deeper into the twisted pines, they were intercepted by an aspect of Tristessa, the Demon of Sadness. Recognizing the group as the catalysts for the city's upheaval, the demonic entity pulled them entirely out of the material world and into her own harrowing realm. The travelers found themselves in a mirror-version of Dresden—a gray, desolate landscape where the weight of existence felt physically crushing.

Within this realm, the party was subjected to a series of psychic trials that forced them to confront depression and sorrow at a scale beyond human endurance. The environment manifested the collective grief of the city's history, dragging the characters into a state of profound emotional paralysis. As they struggled through these trials, the realm provided fractured visions of the city's past during the early Age of Dominion. They witnessed the ancient celestial battle where the Archangel Amandine descended to challenge Tristessa for the devotion of the people, eventually casting the demon down from the heavens into the very forest where the party now stood.

The transition back to the material world bore a heavy toll. While the party struggled through the psychic trials of the mirror-Dresden, the manufactured spirit of Lofta found themself unable to withstand the physically crushing weight of the Demon of Sadness. As the group was pulled back across the veil, Lofta's essence flickered and faded, consumed by the collective grief of the realm. Muddy witnessed this and called out to Amandine for help only to have his prayer unanswered. When the party materialized back in the living world within the cold stone confines of a massive mausoleum at the heart of the forest's graveyard, they were met with a chilling silence where their companion's mechanical chattering should have been.

Inside the mausoleum, they discovered a grand coffin illuminated by a single, persistent moonbeam. Exhausted, hollowed out, and mourning the sudden loss of their biomechanical friend, the group secured the stone chamber to take a necessary long rest before their final descent into the sewers of Dresden. Through a tactical puzzle involving mirrors to divert the moonlight, they eventually forced the coffin open, discovering a divine token leftover from the battle between Amandine and Tristessa a thousand years ago; a fragment of Tristessa herself, a facsimile of shardisite created in the demon's realm to channel her power into the material world. The party dubbed this arcane forgery “sadisite”. Muddy Mittens took note.

During the quiet hours of their vigil, the party was visited by a second celestial manifestation: Jasiri, the Archangel of Courage. Appearing as a vibrant and commanding presence, Jasiri voiced his admiration for their defiance against both the Nightingales and the Demon of Sadness. He declared the party to be his champions in the coming struggle for Dresden's future and, as a physical sign of this divine covenant, he left an actual brand upon each of their palms. This encounter had a profound impact on Stanley the Seer, whose previous religious devotion to Amandine was completely transformed. He officially renounced his old ties and rededicated his faith to Jasiri, embracing the path of courage as the group's primary spiritual anchor.

However, the blessing took a sinister turn for Muddy Mittens. Still disillusioned by the lack of divine intervention during his recent trials, Muddy walked to the mausoleum door and dedicated himself with “old words” while placing his hand upon the stone. Muddy then walked to the waterfront and witnessed a significant manifestation: the sight of footsteps in the water walking toward him. Instinctively taking a defensive stance, he drew his sword, and the presence vanished instantly. In that moment, he recognized it was Tristessa reaching out to him, and with a searing pain, the divine brand of Jasiri on his palm was corrupted and replaced by the Mark of Tristessa. As the party prepared to locate the concealed entrance to the sewers within the graveyard, Muddy began the difficult task of harnessing the newly found “sadisite” and imbuing one of his shortswords with its power. When his ritual was complete he saw his reflection in the still water and attempted to hide the physical evidence of his corruption from his companions. The marks of darkness had begun to circle his increasingly bloodshot eyes, and his hand took on a slow, unnatural blackening where the demonic seal bound itself to his flesh—a secret burden that he resolved to carry.
