From the introduction:
The GameMaster's Apprentice deck is a set of tools meant to be helpful for anyone running a roleplaying game. The randomizers on the cards aren’t linked to any particular game system, setting, or even genre.
The general purpose of this deck is to create and arbitrate the sort of story ideas and decisions often made by a GameMaster, but which can sometimes be randomized - perhaps to make the decision more "fair," or maybe just to help the GM come up with something totally new.
Each of the 120 card faces in this deck contains a set of fourteen randomizers. While each randomizer has a specific purpose for which it was designed, I did my best to make the cards as flexible as possible. How each randomizer, or the deck as a whole, is used depends entirely upon the needs of the group, Game Master, or player using them.
This item contains general instructions and numerous pages of print-and-play components (cards) designed especially for use with ALONe.
