In this supplement for Tales of Gor you join a rebellious inventor on a quest for a mythical lost island and city. Will his technological innovations anger the Priest Kings? Will you fall afoul of the pirates that ply their trade across the Thassa? What will you discover beneath the waves, far from the politics and skulduggery of Civilised Gor? This book also contains information on a (non-canonical) Farther Isle for you to use as a setting or base of operations for your player group.

The Silver Cult thrusts the characters into a conspiracy that threatens to overturn the natural order of Gor and the city of Tharna. Will they side with the revolutionaries who seek to usurp the power of that city, or help crush the rebellion? This supplement also contains rules for slave-breaking and torture, and for encouraging better roleplay through mechanics. Ta Sardar Gor!

A 'side quest' from the line of Tales of Gor adventures, The Game of Worlds is an excellent way to bring Earth-based characters to Gor and set them off on their adventures as an introduction. It starts on Earth and takes them to Gor, in the wake of being caught up in the intrigues on their own world, from there they can return - or stay - to live a life of adventure on a more colourful planet. This booklet also contains non-canonical speculation, rules and ideas for Earth-based campaigns and characters, as well as the interplanetary cold war as it plays out on that world. Ta Sardar Gor!
