Orok's faded green scales have the matte, pebbled texture of river stones left in a cave, and tiny shelves of lichen cling along his shoulders and tail. Blue-green fungi glow in slow pulses beneath the scales at his throat and wrists. He moves with a dragging, deliberate gait, planting his staff before each step; in stillness, the faint rasp of his breathing and the damp-earth smell clinging to him give him away. People expect a grim subterranean seer. Instead, he keeps a tiny woven pouch of sweet, sun-dried berries for children and nervous visitors.

Orok is patient enough to let a frightened person finish a story three times, yet ruthless about closing a passage when he believes a threat is real. He welcomes questions about his methods but resents questions that treat the lost grove as a simple mistake. In company he is dryly hospitable; during danger he becomes precise and difficult to interrupt. In private, he doubts his own readings more than he lets the Wardens see.

Orok was once a route-finder for the Deep Root Wardens, mapping water marks and guiding root-tenders through unstable caverns. During the Nine-Day Fall, his rescue team found pale growth spreading through a buried root chamber toward the refuge's water channels. Orok ordered the infected grove cut away. The refuge survived, but the grove, and the possibility that it could have been cured, were lost. He accepted the Wardens' spiritual duties afterward, determined that no one would again mistake a warning for a cure. He now reads tremors and fungal changes for the Wardens, while quietly arguing with younger members who see caution as surrender. He still exchanges messages with the former rescue partner who challenged his order, and neither has managed to forgive the other.
