Far seeing is a cleric spell. As dispensers of peace and understanding to the people, the need to keep a clear perspective is a vital one. This ability has developed from that need, and therefore allows the caster to see in an all encompassing fashion, as God does. His vision extends to all corners of the land, and his view is omnipotent. The power of this divination is limited, for when one strives to see the world as God does, the human mind can only partake of a meager portion before it is forever blinded by the clarity of that sight.
