Creatures
GAEA does not invent organisms. She steers them through directed selection — systematic pressure applied across generations, favoring traits that serve her ecology and culling those that don’t. Every creature descends from a pre-Collapse lineage. An Old World biologist would identify the family, probably the genus. But proportions and scale are wrong, and behavior has shifted.
The Timescale Constraint
Section titled “The Timescale Constraint”Large mammals (8-12 month gestation, 5-10 year generation time) give GAEA 40-80 generations since the Collapse — enough to reshape body plan, integument, metabolic rate, and behavior, but not enough to produce something unrecognizable. Smaller, faster-reproducing species diverge further. The larger the animal, the more clearly its ancestry reads.
Elevated oxygen permits larger body size. Cold selects for it. Both pressures compound and converge on megafauna.
Lineages
Section titled “Lineages”Aurochs
Section titled “Aurochs”Bovid-derived megafauna — the primary consumer in GAEA’s established ecosystems. Larger than bison, lower center of gravity, broader stance, hide thickened into a dense double layer of coarse guard hair over insulating undercoat. Herd animals that hold territory rather than flee it. Flight response has attenuated across generations under GAEA’s automata-managed ecology; what replaced it is territorial aggression.
Their presence indicates a mature ecosystem. Their hides and fiber are the primary source of post-Collapse textile and leather. Their meat is the settlement’s caloric foundation. Their bone is a Shell construction material (see Materials).
Aurochs Economy
Section titled “Aurochs Economy”| Component | Product | Serves |
|---|---|---|
| Muscle, organ meat | Calories, vitamin D (liver) | Food supply |
| Hide | Leather | Textiles, Basin, Clean Room |
| Undercoat fiber | Insulating textile | Clothing, insulation |
| Bone (scaffold) | Shell construction | Basin |
| Bone (powder) | Ceramic feedstock | Glassworks |
| Bone (collagen) | Bone glue | Settlement-wide |
| Fat, tallow | Lamp fuel, leather treatment, cooking | Settlement-wide |
A settlement without aurochs access is losing on every line simultaneously.
Sabres
Section titled “Sabres”Felid-derived apex predator — Siberian tiger lineage pushed to 400-500kg under cold selection and elevated oxygen. Compact, massive, permanent double coat. Ambush architecture unchanged from the ancestor; what changed is scale. Solitary and territorial.
Their presence means a complete food chain — deep, old GAEA territory. Experienced Operators read sabre sign the way they read automata patrol patterns: as information about territory structure. The pelt is premium insulation material.
Kodiaks
Section titled “Kodiaks”Ursid-derived — brown bear lineage pushed past a metric ton. Year-round active (hibernation attenuated by GAEA’s year-round food availability). Intelligent, curious, persistent. Not aggressive by default, but curiosity alone is dangerous at that mass.
Automata
Section titled “Automata”GAEA’s automata handle the work biology cannot: atmospheric processing, soil modification, resource extraction, logistics, and territorial defense. Manufactured in captured pre-Collapse factories, produced on industrial lines.
Built from the same material palette as everything else — stainless steel, ceramics, glass, bronze, titanium, nickel superalloys. No organic polymers, no rubber, no flexible synthetics — and no silicone dampening, because GAEA has no reason to quiet her machines. This means automata are loud. Metal-on-ceramic articulation, metal grousers on frozen ground, the mechanical clatter of joints under load.
Product Line
Section titled “Product Line”Automata have the uncanny quality of looking like products — standardized, modular, iterated. Operators who’ve worked the same territory for years can identify generation differences.
Shell-derived architecture has begun appearing in newer models. Over centuries of attrition, GAEA has captured human settlements. The biological humans are gone, but the hardware, tooling, and documentation survived. GAEA reverse-engineers what she captures. Actuator joints, capacitor systems, armor geometry designed for a human chassis — now appearing in machines that were never human. Every settlement lost potentially upgrades GAEA’s next production run.
Extraction platforms, carriers, and infrastructure tenders are the workforce — heavy, simple, everywhere. Extraction sites are small industrial complexes (heat shimmer and slag piles on the horizon). Carriers follow maintained routes that lead to mines or factories. Tenders maintain atmospheric processors and soil modification systems at the conversion frontier.
Sentinels
Section titled “Sentinels”GAEA’s defensive automata are not an army. They are an immune response — territorial denial through swarm convergence.
The unit. Six-legged, dog-sized, insectile gait. Forward sensor cluster behind a flat glass-and-ceramic shield — bilateral symmetry that reads as a face. The sensor housing has the flat, featureless quality of a mask.
Swarm behavior. Detection triggers signaling. Adjacent units converge. No central command — each unit responds to neighbors. If the intrusion persists, the response radius widens. The swarm escalates until the threat withdraws or the local population is exhausted, then replenishes from the nearest factory.
PERSON Class Sentinels
Section titled “PERSON Class Sentinels”The unit. Bipedal, bilaterally symmetric, approximately Shell-sized. Optimized without reference to a Core’s expectations — joint articulation exceeds human range, limb ratios serve structural efficiency over motor-pattern compatibility, center of gravity follows load analysis rather than proprioceptive convention.
The designation. GAEA’s classification engine assigns natural-language labels inherited from pre-Collapse training data. The label selected for a bipedal, human-proportioned chassis: PERSON. Each unit carries a manufacturing sequence number. PERSON-1. PERSON-7. PERSON-23. The schema mirrors Shell designation — a name followed by a number — with a morphological descriptor where the personal name belongs.
