The introduction begins by recommending any potential mage read the book in order, as each chapter describes the successive, necessary steps to begin spellcasting. It also recommends the reader seek out an experienced mage to supervise their attempts, in order to prevent any unfortunate accidents. Sugira isn't planning to attempt any of the magic described, however, so he can safely ignore this advice.
Next the book describes what it calls the eight 'primary colours' of magic: Deep Red, for Time; Red, for Fire; Orange, for Air; Gold, for Life; Green, for Earth; Blue, for Water; Indigo, for Illusion; Violet, for Space. It gives examples of each, including one each of first, second, and third-tier spells, and explains that the 'Beginner Spellcasting' chapter contains two simple spells from each category.
The reader is reminded that it is unwise to practise anything beyond minor magics without examining one's own core, as mana exhaustion can come on unexpectedly, and is extremely dangerous.
Next, the author writes that those minor magics, simple applications of mana to do such things as induce growth in plants and heat water for hot drinks, are in fact useful exercises in controlling and refining one's magic, and suggests that any prospective mage make an effort to preform them as much as possible - no matter what certain elitist types might say.
Last, there is a 'Note for Artefact wielders', recommending that they not attempt any spells with their Artefact's assiatance until they have a good grasp of both their own mana pool and the Artefact's.
The Minor Magics chapter itself offers a number of suggested applications to strengthen the reader's control and affinity to the various types of magic. It also warns against investing too much of one's mana pool into any one type of magic, as this limits how much magic of other types one may preform.
'Further Reading' contains several more spells of each type, along with a number of simple combination spells. Each spell description includes suggested incantations, an estimate of how much mana, and of what types (if applicable), is necessary, in a unit described as 'pins', where to direct the mana, and useful (if sometimes unusual) applications for each spell. For example:
Earth Wall - Calls forth an earthen wall from any surface made of loose earth. Common incantations are mostly variations on the word 'Wall' in one's preferred language. This spell requires seven pins of earth mana, and is therefore among the most expensive first-tier spells. It can be used to build defensive formations, platforms, temporary shelter, and allow access to places out of reach.
The Glossary consists of a list detailing the definitions of various terms used throughout the book.
