User summary: This book (in french) mostly deals with the second part of Zelazny's novels (Merlin's saga). There are also suggestions for creating campaigns and additionnal rules about various aspects, including characters from courts of Chaos, and a short scenario. This book is shorter than the english book Shadow Knight, but has hard cover and different maquette. The drawings from Florence Magnin and Philippe Barthélémy are very high-quality, compared to the french core rules book or to the english version.
