The Sihedron Circle is a ring of ancient stone monoliths set on exposed high ground. Each pillar carries Thassilonian markings, and the sevenfold arrangement makes the site immediately recognizable as a deliberate ritual structure rather than a random collection of standing stones. Snow and barren terrain around the circle keep attention on the carved monoliths and the open center they surround.

In Rise of the Runelords: Sins of the Saviors, the site provides a clean ritual and transition space tied to the Sihedron. For a GM, the stones break lines of sight and offer isolated pieces of cover without cluttering the map, while the center becomes an obvious place for a gate, spell or confrontation. It can be reused as an ancient rune circle, mountaintop portal or seven-stone ritual site in any campaign.
