The Disciplines of the Dragon is a Lore book found inside of Chayne's Room.
Upon opening this book, Note to Chayne falls out, beginning the quest: 
Old Friends.
This handbook is dedicated to my oldest and dearest friend, Chayne, and our shared childhood that inspired this publication.
Choosing the sage's Path is a noble one, ideal for any young Majiri looking to aid their community. However, a young sage's choice does not end at one's Path ceremony.
Rite and Ritual
Members station themselves within a town or community, vowing to serve as its spiritual pillar. You will lead the ceremonies your neighbors need, whether they require birthdays or funerals. On more ordinary days, you will still be expected to care for people by providing advice and medicines. There is no place like home for the sage of Rite and Ritual.
Earth and Air
Members travel throughout Palia, living a nomadic lifestyle, as stewards of the natural world. You will keep a careful eye on the health of the environment, learning to care for rocks, waters, plants, and animals. You may be called upon to plant new trees or educate others on the ways of the land. The sage of Earth and Air blossoms when helping Palia grow.
Moon and Stars
Members track the movements of meterological[sic] and planetary bodies to make predictions. On most nights, you will watch the moons and record the signs that Dragon, Maji, sends from the lunar wellspring. During the day, you will interpret your findings into advice for your community. Curious sages will find their place among the Moon and Stars.
Writ and Word
Members devote themselves to study and record-keeping, aiding everyone from civilians to other sages. They create documents and treatises today, so future generations can learn from their ancestors. You will spend your time maintaining archives of knowledge and adding new volumes. A good sage of Writ and Word will go down in history.
