- Physiological Summary
- Trocra is a crystallized colony of cyanobacteria whose bio-mineral matrix is highly unstable. Impact against a solid surface propagates catastrophic fracture through the colony and causes detonation.
Overview
Trocra is a crystallized cyanobacterial colony recorded on the surfaces of the Oubliette. The visible mass is a bio-mineral growth: microscopic photosynthetic or chemosynthetic cells embedded within a rigid crystal matrix produced or accumulated by the colony.
The organism is highly unstable. When detached and driven against a solid surface, mechanical shock races through the crystalline lattice and causes the mass to detonate. This reaction makes a passive wall colony dangerous to handle and easy for a larger threat to convert into an improvised projectile.
No evidence supports the former interpretation of Trocra as an Alimbic ammunition reservoir, energy vessel, or manufactured support organism. Its relationship to the prison is ecological and hazardous; whether the Alimbics cultivated, tolerated, or failed to remove it remains unresolved.
Anatomy And Physiology
A Trocra colony consists of cyanobacterial cells distributed through layered mineral crystal. Cellular films occupy microscopic channels where moisture, dissolved compounds, and radiation can reach them, while continued mineral deposition gives the mature growth its hard angular form.
Instability increases as internal stresses accumulate across the lattice. Fracture at one point can propagate faster than the colony can absorb or redirect the force, releasing stored chemical and structural energy as an explosion. The reaction does not require deliberate behavior.
A fragment may contain living cells even after separation from the wall. Viability and explosive risk must therefore be evaluated independently: dead crystal can remain unstable, and living material can persist in pieces too small to resemble the original colony.
Habitat And Range
Confirmed Trocra growth occurs within the Oubliette, attached to mineral-rich walls and structural recesses around the containment space. Stable atmospheric conditions and long periods without disturbance allow the crystalline colonies to enlarge despite their sensitivity to impact.
The distribution may reflect light, trace chemistry, moisture films, or energy leakage from the prison systems. Mapping colony density against those variables can determine whether the organism occupies the site naturally or was deliberately encouraged in selected positions.
Absence outside the Oubliette should be treated cautiously. Small fragments could travel on equipment or debris without detonating if kept from solid impact. Quarantine surveys should test recovered dust for both cyanobacterial markers and strained crystal microstructure.
Behavior And Ecology
Trocra does not patrol, attack, or defend territory. Its hazard arises from material state: a living colony can remain motionless for long intervals and still become explosive the moment a larger force detaches and throws it.
Within the Oubliette, colonies form part of the environmental threat available to Gorea. The prisoner can exploit them as projectiles, but that use does not prove they evolved or were installed as weapons. It shows only that their instability can be weaponized.
The organism may influence surface chemistry by concentrating minerals and excluding less tolerant films. Mature colonies also create no-contact zones for mobile life, since collision can destroy both the Trocra and anything nearby.
Reproduction And Development
Growth begins as a thin cyanobacterial film on a suitable mineral surface. As the colony expands, metabolic products and local chemistry promote increasing crystallization until the mature mass becomes rigid, angular, and dangerously stressed.
New colonies may arise through cell dispersal or nonexplosive fragmentation, although direct reproductive observation is absent. Any viable fragment that settles without strong impact could seed another growth if moisture and mineral conditions are favorable.
Development should be studied in place. Removing a mature colony destroys spatial evidence and risks detonation, while early films can be mistaken for ordinary residue. Sequential imaging offers the safest method for measuring growth rate and identifying the point at which the crystal becomes unstable.
Crystallized Cyanobacterial Colony
Trocra is a colony of cyanobacteria enclosed in a rigid crystalline matrix. The archive classifies the colony as a bio-mineral organism rather than a storage vessel: its apparent shell is accumulated biological crystal, and no internal ammunition reserve or Alimbic manufacturing system is present.
Individual microorganisms cannot be assessed meaningfully apart from the colony. Their collective growth produces the visible body, concentrates reactive compounds, and creates the unstable fracture planes responsible for the hazard. Samples must preserve both cells and crystal lattice.
Impact Detonation
The crystalline mass is highly unstable and detonates when it strikes a solid surface. Mechanical shock propagates through the colony faster than the matrix can release strain, converting a passive wall growth into a violent blast.
Detached material remains dangerous regardless of whether the bacteria are metabolically active. Handling equipment must prevent collision with floors, containers, and other specimens. A colony that appears desiccated can retain enough structural tension to detonate during transport.
Oubliette Hazard Ecology
Trocra colonies persist around the Oubliette, where sealed conditions and mineral-rich surfaces support crystallization. Their placement provides abundant unstable masses that a powerful organism can tear free and use as projectiles, turning environmental growth into part of the containment threat.
The colonies should not automatically be interpreted as deliberate Alimbic weapons. Their hazard may have been tolerated, cultivated, or merely exploited after the prison was sealed. Growth rings, attachment chemistry, and relation to damaged architecture are the best evidence for distinguishing those possibilities.
