A handwritten book (The Prisoner of Glouphrie)

A handwritten book is a book obtained during The Prisoner of Glouphrie and used in Bolrie's lab when building an anti-illusion device. The book contains notes about the workings of illusion and how to build an anti-illusion device.

The book is 52 pages long and has an introduction page and an index, followed by 11 chapters:


 * Illusion theory: Bolrie introduces his theory on how illusions work and his plans to make a portable device that uses coloured light to counteract the light of illusions to temporarily dispel them.
 * Crystal singing: Here Bolrie writes about how he learned of singing crystals into the shapes of coins and bowls. He documents his experimentation with dying coins different colours and how he discovered the method of using light and prisms to change the colour of the crystal bowl and coins. He discovers 42 possible coin types, with 7 possible colours and 6 possible shapes.
 * Colour theory: Bolrie notes that light comes in only the 7 colours of the rainbow, yet illusions utilise a much wider array of colour, so he hypothesizes that this is achieved by combining the shades. Ilfeen shows him a 6 sided colour wheel, and he notes that opposing colours cancel each other out, and that red, green, and blue can be combined to make the other shades.
 * Spotting illusions: To be able to spot illusions, Ilfeen convinces elf trackers to teach Bolrie their secrets. After years of learning, it pays off, and he discovers a pebble that has an illusory appearance.
 * Experimenting: Bolrie experiments on the pebble by focusing cyan, magenta, and yellow light at the pebble to try and affect the illusion. He can only manage to make it waver, so to change the frequencies and secure the setup, he decides to build a housing structure for the crystals.
 * Building the device: Bolrie succeeds in building a "Working portable illusion device," and details the supplies needed to construct it. He still has not managed to perfect the intensities, but works on calibrating it later.GlouphrieAppendixA.jpg
 * Calibration: After trying every light combination, Bolrie discovers that the quantities of each type change regularly. To solve his problem, Ilfeen gets him a calibration box built by Yewknock. He then describes how it measures the intensities of light required to dispel the illusion. To do so, he must combine two coins of specific colours and shapes to match the output colour. The specific coins used can be determined by the sum of their output intensities, which are the products of the number of sides and the colour value (1-7, 1 being red, 7 being violet).GlouphrieAppendixB.jpg
 * Colour mixing: In this section, Bolrie documents the specific ratios of light colors that can be combined to make the right shades of cyan, magenta, and yellow.
 * Arposandra: Bolrie has finally found the entrance to Arposandra. This is the last chapter because he is captured and held prisoner once he enters the city.
 * Appendix - Shapes: This section diagrams how different water levels in the bowl produce different coin shapes.
 * Appendix - Colours: This section has a diagram of each colour and its numerical value ranging from 1 to 7.
