Summaries
Illusion of the End
The shadow of the Lord Ravager loomed over Planarcadia, and the restless Voracity husk threatened the safety of the entire planet. Before you set off for the mysterious World in Canvas, the Express Crew threw a farewell celebration for you in the Party Car.
Living Sacrifice for Gods and Mortals
Living Sacrifice for Gods and Mortals
Yao Guang had deployed the Deca-Light Reflection Barrier in Planarcadia to monitor Asat Pramad's movements. At Yao Guang's suggestion, Blade and Silver Wolf headed to the World in Canvas to find the maw of Voracity.
Arcadia of Mystery and Terror
At the "World's End" Tavern, Ashveil's investigation uncovered an inextricable connection between the Masked Fool "Enroute," Navigator "Isee," and Lord Ravager "Asat Pramad." At the moment of revelation, an unknown, powerful force swept Ashveil away.
Best Farewell to the World
You traveled alongside Nihilux, who was overdue on her artwork, to the final stop before encanvasing — the Inkford Hermitage hotel. You gathered intel about Graphia from all over the hotel, eventually managing to summon "Graphia" and learning of the method to enter the World in Canvas.
Primeval and Other Times
Aboard Graphia's ferry, you, Blade, and Silver Wolf arrived at the Meadow on the Distant Shore within the canvas and found the maw of Voracity. To obliterate Shuhu's flesh, Blade leaped down into it, plummeting into a perilous path of near-certain death.
Yesterday's World
To investigate the suspicions surrounding Ryusuke, Himeko invited him for a chat and accompanied him on a tour of the Astral Express and Graphia Academy. Ryusuke confessed that he was afflicted by the Weathering Curse while investigating the Destruction, and hoped Himeko could reveal the truth behind the Bloodstained Games from fifteen years ago.
Non-Existent State
Within the beastly maw of Voracity, Blade imprisoned Shuhu within his own body, forging his own rebirth. After Himeko exposed his disguise, Asat Pramad cast aside all concealment. Manifesting simultaneously across multiple locations in Planarcadia, he declared he would bring the overdue "Destruction" to all life in the arcadia.
