Maps and Books
In the world of the Prophecy, maps and books are valuable items that are rarely seen. Most of them were destroy during wars. Even inaccurate maps are cherished by the Warlords who possess them and are considered war secrets. The Oldest maps are generally the most detailed, but are often contradicted by newer ones.
Spell books and ritual scrolls are jealously guarded by the very few who have “the gift” of magic. Being able to read and understand them is no guarantee that one can succeed in casting the spell they describe.
