Edgerammer (Shelfocetus rictus)

Alias: None
Origin: Kela (polar shelves)

The Edgerammer is a massive aquatic creature native to the polar shelves of Kela, known for its ramming behavior that collapses coastal routes and ice shelves. Its robust, streamlined body and powerful head structure enable it to break through ice and rock, creating hazards for coastal expeditions. Non-aggressive toward humans but highly destructive due to territorial movements, it was historically feared by Kela’s tribes and depicted in carvings as a force of unstoppable change. Its presence indicates stable, cold marine ecosystems and poses risks to navigation and infrastructure.

Terrain

Inhabits icy polar shelves and coastal waters of Kela. Thrives in cold, high-pressure marine environments with abundant ice and rocky outcrops. Frequents shallow shelf waters and ice-bound coasts. Avoids deep open oceans and terrestrial biomes.

Elevation

Found at shallow ocean depths, typically from sea level to 0.5 km below. Rare beyond 1 km where ramming substrates are absent.

Climate

Kela’s polar climate, averaging -30 to 0°C, supports the Edgerammer’s physiology. Stable, low-visibility polar conditions favor its habitat. Struggles in warmer or humid regions.

Weather

Adapted to frequent snowstorms and icy winds. Seismic activity can agitate individuals, triggering ramming that collapses coastal routes. Stellar disruptions rarely affect polar habitats but may alter ice stability.

Lifespan

Lives 80–120 Geban years. Slow growth in the first 15 years with peak ramming activity after maturity at ~20 Geban years. Reproduces infrequently.

Length / Size

Mature Edgerammers measure 12–14 meters in length. Juveniles range from 5–8 meters.

Weight

Estimated at 15–20 tonnes, reflecting a dense, muscular structure optimized for breaking ice and rock.

Uses

• Ecological role: Reshapes coastal shelves and creates niches for smaller marine fauna.
• Geological indicator: Presence signals stable, icy shelf systems for coastal surveys.
• Cultural symbol: Depicted by Kela tribes as emblematic of relentless force and change.
• Guidance: Avoid crossings near active ramming zones; monitor ice stability to predict behavior.

Notes

The Edgerammer’s ramming behavior complicated coastal exploration during the Era of Absolute Expansion (~3,000 YBM). It reshapes polar shelves and endangers infrastructure. Partial retrievals limit anatomical understanding. Use seismic and ice sensors to avoid active ramming zones. Range is restricted to Kela’s polar shelves.
