Ringmaker is the title given to who creates the Ring of Possibility of a vespromancer, usually a Sulfea.
A vespromancer’s ringmaker is akin to his master, teacher and sometimes confidant, even if relationships between the sulfee and the mortals are often troublesome.
Sulfee
The Sulfee are the original ringmakers, but they are known to give their power to very few and never to many persons at once. This is in part due to the fact that they consider useless to teach one who doesn’t exhibit any talent, but the main reason lies in the price a sulfea has to pay to create a Ring of Possibility.
When a sulfea creates a Ring of Possibility, she does so by sacrificing a substantial fraction of her power, which reders her weaker.
