Its a special book held by some Snake Cult troops and can be sometimes found in the loot. They are useless until the players reaches 500 renown and joins a KHO. You can trade these books with the knight of the KHO you belong for more denars, relation with the order and rank points. They can be dropped by:
- Serpent Priestess
- Maltise (double the chance, if very lucky, she can even drop 2).
- Azi Dahaka Serpent Priestess
Each will award you 1000 denars, 1 relation point and 3 rank points.
