Chapter Summaries

Tierra led Hermione to the Room of Requirement to prepare for brewing the Philosopher’s Stone and explained how it could provide the necessary equipment and alchemical arrays. He also revealed that Hogwarts’ founders had created the Room as an independent space and that Slytherin suspected Gryffindor, Hufflepuff, and Ravenclaw might still live within it.

• Tierra explained that brewing the Philosopher’s Stone required extensive equipment, ingredients, materials, and alchemical arrays, and that the Room of Requirement could supply much of what they needed.
• Tierra told Hermione that the four founders had severed a portion of space from the world and anchored it to coordinates in a Divine Dimension.
• Tierra explained that the founders had attempted to achieve immortality by attaching fragments of their souls to the space, but the fragments became part of the Room of Requirement’s system.
• Tierra said Slytherin had withdrawn into the Chamber of Secrets after losing his sanity and did not know what became of the other founders.
• Tierra revealed that Slytherin suspected Gryffindor, Hufflepuff, and Ravenclaw were still living inside the Room of Requirement, beyond aging, death, disease, and time.

Tierra showed Hermione how the Room of Requirement could create precise conditions for refining the Philosopher’s Stone and explained why its magic required careful control. He brought her inside to observe Horace Slughorn brewing a solvent, then began teaching her alchemy.

• Hermione reacted with alarm when Tierra said Godric Gryffindor, Helga Hufflepuff, and Rowena Ravenclaw might still be in the Room of Requirement.

• Tierra warned Hermione that her uncontrolled thoughts could alter the room’s conditions and gave her a diadem to isolate them.
• Tierra explained Slughorn’s Alpha-36 solvent and its brewing requirements, then offered to teach Hermione alchemy before she could begin experimenting.

Tierra taught Hermione about the Divine Dimension and the Three-Dimensional Origin, explaining their role in the Godhood Ascension Ritual. He left her with the reason each Philosopher’s Stone must be recalculated: people change within the three dimensions, making the unchanging origin appear different from their perspective.

• Hermione explained the Material, Spiritual, and Spiritual Dimensions, and Tierra introduced the Divine Dimension as the dimension of universal laws that could preserve consciousness.
• Tierra outlined the two challenges of the Godhood Ascension Ritual: reaching the Divine Dimension and preserving an identical consciousness there.
• Tierra explained that the Three-Dimensional Origin was the perfect fusion of the three lower dimensions, and that the Philosopher’s Stone acted as a gate to the Divine Dimension.
• Tierra asked Hermione why alchemists had to recalculate the Philosopher’s Stone instead of copying their predecessors’ work; Hermione could not answer.
• Tierra explained that people changed along with the three dimensions, so the eternal Three-Dimensional Origin appeared to change relative to them.

Tierra explained how refiners calculated their personal trajectories and used them to plan experiments, then arranged for Hermione to study Horace Slughorn’s potion brewing and paid her for her work. As Hermione questioned the Magical Federation’s self-defense laws, Tierra challenged her assumption that stability should outweigh everything.

• Hermione asked how refiners could determine the Divine Origin’s coordinates, and Tierra explained that mathematical models helped them calculate their trajectories and plan experiments.
• Tierra told Hermione she would learn from Horace Slughorn’s brewing and later help with calculations, and he persuaded her to accept wages by citing the Magical Federation’s labor laws.
• Tierra explained the conditions for brewing Alpha-36 solvent and described Horace Slughorn’s Heimworth Brewing Method while Hermione watched.
• Hermione asked Tierra whether the laws protecting workers through self-defense could cause turmoil in wizarding society, and Tierra challenged her concern about prioritizing stability.

Tierra explained that Hermione could not perceive the Divine Dimension from within the dimensions of matter, spirit, and mind, and that creating a Philosopher’s Stone required all four elements to overlap perfectly. He demonstrated a stone made through his own divine power, showing how it became an unstable singularity when released before restoring his body.

• Hermione asked Tierra why he could not simply create a Philosopher’s Stone despite being a Divine Being.
• Tierra showed Hermione the origin point of the Divine Dimension at his fingertip, which she could neither see nor sense.
• Tierra explained that a Philosopher’s Stone required the perfect overlap of matter, spirit, mind, and the Divine Dimension’s origin point.
• Tierra used his power to create a blood-red Philosopher’s Stone, sacrificing his flesh until only his skeleton remained.
• When Tierra released the stone, Hermione perceived it as an all-encompassing singularity, and Tierra snapped it back into his hand.
• Tierra clenched the singularity, causing it to explode outward and restore his body, then explained that such a stone became a singularity when it left a Divine Being’s control and contacted external matter, spirit, or mind.
