Magrallen

The Magrallen is a device dating back to the time of the dreamers, when magisters could enter the Fade at will and control people's minds. Magister Aurelian Titus sought to empower it with King Maric Theirin's blood in order to augment his cult of dreamer's power so that they can brainwash and mind control of Thedas for the glory of the Tevinter Imperium. It was eventually destroyed by Alistair.
