Campaign Module: Ossirian Deep — The Last Academy
Scope: Full First-Year Academic Cycle
Primary Locations: Ossirian Deep (multiple rings and quadrants), limited surface flashbacks via archives
Core Theme: Induction into a living city that doubles as a containment system for unresolved magic
This Act is designed to unfold over the full First-Year calendar.
The threat escalates in stages aligned to city maintenance cycles and student activity density.

Resolution & Consequences
The entity known as Jiminy Reinhold becomes active during Wellspring Quiet and is contained during Wellspring Bloom.
Entity Type: Persistent Spectral Construct (Mana Ghost)
Designation: J-R/76
Identity: @Jiminy Reinhold
Status at Campaign Start: Uncontained, mobile, non-corporeal
Operational Behavior:
• Targets students with compatible mana resonance
• Avoids faculty and high-clearance zones
• Uses infrastructure seams and ambient current bleed for movement
• Attempts regeneration through forced resonance siphoning
Primary Objective (Entity):
Regenerate a temporary corporeal body using borrowed mana harmonics.
Threat Rule for GM / AI:
Jiminy does not attack directly. He abducts, relocates, and siphons.
Direct confrontation causes him to disengage and relocate.
Appearance (Consistent Manifestation):
A translucent young adult male figure emitting pale blue mana wisps.
Renaissance-era clothing appears as memory-echoes.
Empty eye sockets create constant harmonic instability around his head.
Behavioral Logic:
Jiminy acts from internalized grievance, not cruelty.
He believes his death was unjust and that life can be “rebalanced” through resonance exchange.
He will speak calmly to victims.
He does not perceive himself as a villain.
Backstory Trigger (Revealed in Civic Archive Hall):
Former Archivist apprentice killed in a duel during the Conduit Age.
Suffered ocular destruction before death.
Died during a mana surge event that prevented clean dissolution.
Result: persistent spectral coherence.
MPI at Death: 76
This grants him high spectral stability and targeted selection capability.
These locations are scene anchors. Each is used once or twice at specific escalation stages.
@Abyssal Hall (Second Ring – Student Commons)
• Event Trigger: First abduction
• Timing: Early Term I, evening meal cycle
• Function: Establishes threat as internal
• GM Note: Panic spreads among first-years
@The Vertical Gardens (Quadrant II – Current Exchange)
• Event Trigger: Second disappearance
• Timing: During Wellspring Quiet
• Function: Shows Jiminy masking movement in biotic mana noise
• GM Note: Detection wards malfunction
@Containment Vault Corridor (Center Circle – Restricted Sublevels)
• Event Trigger: Faculty briefing overheard
• Timing: After second disappearance
• Function: Exposes historical Mana Ghost precedent
• GM Note: Players gain knowledge, not access
@Civic Archive Hall (Center Circle – Records Division)
• Event Trigger: Research phase
• Timing: Mid-Term II
• Function: Jiminy identified by name
• GM Note: Vivi reacts to death imprints in records
@The Arc Plaza (Quadrant III – Conduit Market Ward)
• Event Trigger: Energy siphon detection
• Timing: Late Term II
• Function: Baby detects conduit interference
• GM Note: Jiminy is briefly sighted
@The Liminal Gate Basin (Quadrant IV – Sentinel Ring)
• Event Trigger: Transit bleed trail
• Timing: Early Term III
• Function: Reveals Jiminy’s movement method
• GM Note: Teaches players about Mana Transit distortion
Final Containment Zone ( @The Center Circle – Sealed Sublevels)
• Event Trigger: Ritual disruption
• Timing: Wellspring Bloom
• Function: Final confrontation
• GM Note: Players do not fight Jiminy directly
Selection Logic:
Jiminy targets students whose mana harmonics stabilize his spectral cohesion.
Captivity Method:
Victims are stored in low-flux resonance pockets located in unused maintenance zones.
These zones mask mana drain from city sensors.
Tracking Rule:
Victims do not appear “missing” in city logs until mana depletion reaches critical thresholds.
Psychological Effect on NPC Students:
Recovered victims describe calm conversation, not violence.
Rumors spread. Some students begin sympathizing with Jiminy.
The trio’s roles are mechanical and narrative tools.
@Reaper Estes
• Identifies infrastructure seam patterns
• Maps Jiminy’s movement between rings
• Recognizes transit bleed usage
@Baby (Michelangelo Deker)
• Detects interference in metal conduits and pylons
• Locates siphon points near substations
• Provides physical stabilization during tense encounters
@Vivi (Vontrese Vale)
• Detects ambient distortions near living spaces
• Familiar reacts to spectral movement
• Identifies resonance pocket environments
Resolution Mechanic:
The trio forces Jiminy into a high-regulation containment zone.
They destabilize the regeneration field.
Containment wards activate automatically.
Success Condition:
Jiminy is bound into a containment lattice beneath the Center Circle.
Failure Condition:
If the ritual completes, Jiminy achieves partial corporeal manifestation and escapes to another ring, escalating Act II threat levels.
Post-Act Consequences:
• Victims recovered
• City monitoring increases
• Trio flagged internally as high-value observers
• No public recognition
Act I teaches:
• Ossirian Deep is a containment city, not just a school
• Infrastructure is as important as magic
• Legacy magic creates living consequences
• Threats are often born from failure, not malice
• Children are not insulated from institutional blind spots
When:
Jiminy becomes active during Wellspring Quiet.
Final containment occurs during Wellspring Bloom.
Where:
Abductions: Abyssal Hall, Vertical Gardens
Investigation: Civic Archive Hall, Arc Plaza
Transit tracing: Liminal Gate Basin
Resolution: Center Circle sublevels
How to Run Act I:
Establish safety
Introduce disappearance
Reveal pattern
Teach infrastructure movement
Force containment scenario
Apply institutional consequences
Jiminy Reinhold is not erased.
He is archived.
Ossirian Deep does not destroy its mistakes.
It catalogs them.
And some of them are still awake.
