The ritual magic system in Vale has different colours of magic to represent different things. This little dohicky shows what each kind is for, and also shows the rotation of magic around the great wheel. It's made of Birch and the grain from each section is aligned to point towards the centre. 0.8mm ply holds each of the mana crystals into place and because they're translucent you get a really nice shiny effect when you hold it up to the lights (It also helps to differentiate between the Pink/Red and Blue/Light Blue gems)
