Strength of Thousands Player's Guide

From the Introduction:

The Magaambya is perhaps the greatest and oldest academy of magic in the world, and its students know they are supported by the strength of thousands of students who’ve come before them. History, magical lore, and much more can be found within the walls of the school, but students of the Magaambya aren’t confined to the campus. They are expected to learn from, and share knowledge with, the wider world—and that wider world has plenty of adventure to offer!
