The torc of the archprelates was a ceremonial necklace which was passed down from Archprelate to Archprelate during the Church era. After the Church era, in the early 580s it was stolen from the last Archprelate and used to by the Nihilists to release the Marvinogian, a multi-headed being of immense power which had been sealed away by Dunamis. The torc was recovered later by officials of the Citadel of Light.
