From the publisher's website:
In Chronicles of the Gatekeeper, an adventure supplement for the Star Wars: Force and Destiny roleplaying game, the holocron of a mysterious, vanished Jedi Knight surfaces. Its Gatekeeper offers to instruct you in an incredible Force power and leads you on a perilous interstellar quest in which every choice you make can affect countless innocent lives– and profoundly alter your destiny.
This 96-page, beautifully illustrated book introduces locations throughout the Star Wars galaxy, a new playable species, and a wide range of adversaries from local matriarchs and Clone Wars-era droids to sadistic criminals and vicious wild beasts. Designed to be used with the Force and Destiny roleplaying game, Chronicles of the Gatekeeper can also easily be integrated into an Age of Rebellion or Edge of the Empire campaign.
