Ketek Arzun is a broad-shouldered human with weather-browned skin, close-cropped black hair, and a thick, carefully trimmed beard threaded with a few early silver hairs. He wears worn leather armor beneath a green-gray travel cloak, its seams repaired with different shades of thread. His hands are large and rough from climbing, trapping, and working with plants. Within a minute of meeting him, most people notice the way he stands with his weight slightly forward on the balls of his feet, as though every pause is temporary and he might move toward the nearest sound. When he walks, he favors his left side on steep ground, not from injury, but from a lifetime of carrying packs and shelter poles over his right shoulder. A carved walnut pendant shaped like a mountain seed hangs at his throat.

Quietly attentive and practical, Ketek notices small changes in weather, posture, and animal behavior before he notices social formalities. He is patient with frightened people and inexperienced travelers, but his calm becomes hard-edged when someone acts carelessly. He has a dry sense of humor and prefers useful conversation to polite chatter.

Ketek Arzun was born in a small human settlement tucked beneath high, wind-cut ridges where shepherd paths crossed old hunting trails. His family moved with the seasons, guiding caravans through mountain passes and gathering medicinal roots from valleys that most travelers never noticed. As a child, Ketek learned that the land spoke through absences as much as through signs: a silent stream, a missing birdcall, or hoofprints that ended too neatly beneath a stand of juniper. He became the one people sent ahead when weather turned dangerous or when a traveler failed to return. During a harsh spring, a landslide buried part of his settlement and poisoned the lower grazing fields with exposed mineral runoff. Ketek survived by leading several families through a forgotten ravine to a warmer valley. There he met an aged druid who taught him the first principles of Druidic, the names of local spirits, and the discipline of taking only what could return. Ketek eventually left the valley to travel beyond his homeland, believing that the same careless forces that damaged his village were spreading wherever people treated wilderness as an obstacle rather than a living neighbor. He now walks the roads as a guide, healer, and watchful protector, carrying his old mountain customs into unfamiliar lands.
