Stonefern (Lithofern rigidus)

Alias: None
Origin: Ngorrhal (rocky cliffs)

The Stonefern is a rigid, fern-like plant found across the frost-covered cliffs of Ngorrhal. Its hardened fronds resemble sculpted stone and help stabilize rock faces against erosion and collapse. Its resilience has made it a trusted trail marker and utility anchor for Frost Sentinels navigating high-altitude passes.

Lifespan

Lives 30–50 years. Matures at 6–8 years. Produces spores in calm seasons.

Uses

Notes

Documented in the Era of Absolute Expansion (~3,000 years before modern Geba), Stoneferns stabilize Ngorrhal’s cliffs. Extant and resilient.
