Hecademia is a simple system (1d4 rolls with addition/subtraction modifiers, playing card-based magic mechanics, set DCs) for running magical adventures in a school setting.

Earth and Hecatei used to be one world in one universe, but ten thousand and five years ago, the worlds were split apart by a magical incident. Five years ago, rifts began to open connecting the two worlds, and despite the efforts of humans and Hecateians, these rifts could not be controlled or closed. Eventually, Earth governments found out about the rifts and the whole thing went public. Today, everyone's world is about twice as big as it was five years ago. Anyone can cross over freely, and many do.

You play as students, human or Hecateian, learning to cast magic at one of Hecatei's many educational institutions, and having adventures along the way.

This 65-page book contains the character creation process and rules of the game, four example schools, faculty, students, adventure hooks, and random event tables.

It also contains lore for Hecatei, including a short history, Hecatei's economic and geopolitical systems, what magic can and cannot do, and a map of Hecatei, including short descriptions of every nation and city-state in the world.

It's a thoroughly built world, with enough space for you to create your own adventures. I hope you enjoy it!
