Vespromancy is the study of the Vesper and the art of manipulating it. It is one of the forms of Magic present in Allyria.
Those who practice vespromancy are known as Vespromancers.
Vesper Chants
The Vesper Chants are the oldest form of vespromancy, the one tought directly by Visenna before the Defiance. They are spells that can be cast even by those without a Ring of Possibility but have extremely specific effects that cannot be modified by the caster.
There exists a great number of Vesper Chants and many vespromancers are still searching for new and lost ones. These kind of spells has never be reproduced by modern vespromancy, who also has difficulties explaining their principles.
Most academics believe that Vesper Chants are incantations created by Visenna, who made them instrinsic rules of the world. If modern vespromancy is the art of modifing reality to make the impossible possible, than the Vesper Chants are possibilities that have been hidden in the fabric of reality.
The greater number of Vesper Chants are simple — some would say useless — spells, mostly useful in everyday life.
