Mirrors: Gabriel's Horn introduces us to a alternative setting for Chronicles of Darkness. The realm of Gabriel's horn is a prison for mortals whose sins are so great that darkness claims them, trapping them in a dark reflection of the world. The book provides alternate character creation rules, along with rules for spirts, ghosts, and the sins that make up rest of the realm.
The Tabletop Gaming club loved the setting presented in this book. A skilled storyteller can use this setting to bring out the psychological horror of realizing your trapped... you're friends aren't your friends but mere manifestions of the realm... We strongly recommend this book.
