Magic, one of the world's great powers, has always fascinated the people of Asterion. It seemed so omnipotent, so tempting—with its help, anything was possible. However, everyone who delved into its study soon discovered how complex and unpredictable it could be. Mastering magic and forcing it to serve a wizard's mind is impossible. There are only better or worse sorcerers and witches who learn a certain number of spells, but none of them truly understand the essence of magic. Yet, they strive to push the boundaries of knowledge and experience further, hoping to shed at least some light on the unexplored realms of the magical domain.

There are many ways to study magic, practice it, and gather the energy needed to cast spells. This module describes the most significant methods and mentions those less commonly used. It will change your perspective on magic itself and how wizards practice it. The gray, faded archetype of the wizard is replaced by many diverse, distinct, and colorful forms. A significant portion of the text also covers psionics, which is increasingly seizing power in Plavena at the expense of magic.

This module also includes the next part of Klíč bytostí astrálních (Key of Astral Beings), or A Ghost Hunter's Guide to the Creatures of the Shadow World, dedicated to the beings that wizards summon from the Shadow World, along with the adventure The Sorcerer's Apprentice.
