Darkroot (Radicor colossum)

Alias: None
Origin: Geba (planet-wide, subsurface caverns)

The Darkroot is a massive, subterranean creature native to Geba’s planet-wide subsurface caverns, known for its digging behavior that collapses galleries and reshapes underground ecosystems. Its robust, limbless body burrows through collapsed exo-core layers and mantle outgassing zones, creating tunnels that house entire ecosystems. Non-aggressive but highly destructive due to its size, it was historically feared by early Geban explorers for destabilizing cavern structures. Its presence indicates active geological zones, making it a critical marker for subsurface surveys, though it poses significant hazards to expeditions.

Lifespan

Darkroots live 50–80 Geban years, with slow growth in the first 10 years and peak digging activity thereafter. They reach maturity at 15 Geban years, reproducing infrequently due to their solitary nature.

Uses

• Ecological role: Creates tunnels that form habitats for degenerate pre-human species, aiding subsurface biodiversity.
• Geological indicator: Presence signals active, mineral-rich cavern systems, guiding mining and survey efforts.
• Cultural symbol: Early Geban tribes viewed Darkroots as omens of instability, incorporated into cautionary lore.
• Guidance: Test ground stability before entering caverns; avoid areas with fresh Darkroot tunnels to prevent collapse.

Notes

The Darkroot’s gallery-collapsing behavior made it a significant hazard during the Era of Absolute Expansion (~3,000 YBM), slowing subsurface exploration. Its role in creating cavern ecosystems supports species like the Neron, though its destructive digging complicates expeditions. Partial retrievals due to damaged remains limit anatomical understanding, as seen with the Boughstrider. Expedition teams should use seismic sensors to detect Darkroot activity and avoid unstable tunnels. Its exclusive subsurface range restricts its impact to Geba’s cavern biomes.
