Great Stones of Nemeton

The Great Stones of Nemeton were a place of worship in the time of the Old Religion.

According to Gaius, who had taken parts in such ceremonies, long before the time of the Great Purge, each year at Beltane the High Priestesses would gather at the Great Stones of Nemeton and summon the spirits of their ancestors using the Horn of Cathbhadh.

Because of the pain caused by the untimely death of his father, Arthur decided to set off for the Great Stones of Nemeton and use the Horn of Cathbhadh to open the doors of the Spirit World, creating a gatewaythat allowed him to talk to Uther Pendragon (The Death Song of Uther Pendragon).
