The Auguries are an ability certain girls from the Marsh, the surrogates, have.
First Augury - Colour
This Augury allows the surrogates to change the colour of an object. They use it to influence a child's skin colour, hair colour, eye colour etc. This is known as the easiest Augury of the three and is the Augury all surrogates learn first when they start their training. This is also the most superficial Augury of all and may not be considered important.
Second Augury - Shape
This Augury allows the surrogates to change the shape of an object. They use it to influence the length of a child's legs, the shape of its face, the size of its organs etc.
Third Augury - Growth
This Augury allows the surrogates to grow things faster and better. They use it to influence the speed with which a child will develop, the child's personality, creativity, intelligence, ambition etc. The Third Augury is valued a lot by the mistresses as it affects their child's mental stability and health. This is the Augury which Violet Lasting has a perfect score in.
