Book of Vitiris
The Book of Vitiris is an ancient spell book, crafted by the great wizard Titus. In it he placed the Ritual which could be used to banish The Demon Prince for 1,000 years.
He used this Ritual to banish The Demon Prince and end The Reign of Terror. Thus was the First Age of Rodinia ended.
Titus then hid the Book, along with the only thing which would open it, the Key of Seven Stars, ready for its recovery nearly one thousand years later by The Fellowship of the Sun.
