Cyrinishad

The Cyrinishad
An unholy tome created by Rinda the Scribe under the forced divine guidiance of Cyric.

Creation
The tome was made for the sole purpose to increase Cyric's power in Faerûn. After the Time of Troubles the power of a deity is directly related to the size and devotion of the worshipers. The tome will turn anyone reading it into a devout whorshiper of Cyric and thus increase Cyric's power. The tome is of great power and once you start reading you cannot willingly stop, and it even works against other deities. The final version of the Cyrinishad was the 398'Th version, and all the previous authors had suffered greatly for their failure to satisfy Cyric.

Appearance
The book is made of raven-black leather, embossed with a pattern of small ginning skulls and sunburts against a twisting, wraped background of torture and chaos. The book has golden hinges and clasps, and it is closed with a lock of unbreakable metal. A child fist seized skull dominates the front cover, the skull animated by Rinda's blood is the guardian of the book and prevents it from being destroyed or removed from the mortal realms.

History
After Mask managed to trick Cyric into leaving the book in his hands it was given to Rinda the Scribe for safekeeping, protected and concealed by Oghma. Later Gwydion the Quick joined Rinda as guardian of the book. They kept it hidden for Cyric and his followers for a long time, until Malik el Sami yn Nasser(who would later become Seraph of Lies) managed to track them down at Candlekeep. Though both Rinda and Gwydion were slain the Cyrinishad was lost near Candlekeep and has yet to be found.
