Born from ancient mountain spirits during the Great Petrification, this otter knight gained stone-infused bark armor while guarding sacred groves. When dark forces threatened to drain life from the highlands, it merged with bedrock through eternal vigil. Now sustained by mineral springs and moonlight, it stands guard where forests meet stone.

Petrified oak plates form interlocking armor that regenerates when near minerals. Crystal formations grow along its joints, refracting light into protective barriers. Its stone-infused fur provides camouflage against rockfaces, while moss-covered gauntlets enhance grip strength. The entity moves with surprising fluidity despite mineral weight, leaving faint crystalline trails.

Guardian of mountain passes and highland forests where stone meets soil. Maintains balance between geological forces and living ecosystems by preventing erosion disasters and containing underground disturbances.
