Magonism is the name of using wind captured in satchels (and of capturing them). It is an art started in the dawn of mortality when a forgotten hero captured the Four Winds in a bag and used them on a series of adventures to help his people. Magonism is the name given to this art by the esotericists at Simon Island Academy. It is said the art truly originated among the 'Ahl Al-Riyh (People of the Wind), and its proper name is Sahar Al-Rayah. Others still say it was invented by falcon folk or sylphs.
