This life came to an end when a massive Grarg army invaded, seized the land, took the Stone, and eventually murdered the queen. Now the Sylvani live as slaves under the merciless overlord Ogban and his murderous Grarg thugs. Ogban uses the power of the Stone to bring destruction on the families and friends of anyone who opposes him, and thus he suppresses any resistance.
Queen Pari Sylvan left behind a baby son called Kylar. Before she died she had locked into the mind of Kylar a secret: her royal ancestors had given the people certain magic objects the combined power of which would overcome any evil force controlling the Stone of Destiny. Over the centuries the whereabouts of these seemingly insignificant objects had been forgotten. On becoming a young man Kylar Sylvan set off to try and find these objects, but just when the Elders sensed that he was on the brink of success he was murdered by one of the Grarg thugs. If he had recovered any magic objects these objects would have immediately returned to their resting places.
Since this tragedy the Elders have revealed the quest to a succession of true and worthy Sylvani: all have failed. Now they plead to anyone who will listen.

From the blurb on the back of the book:
The Mystery Of Silver Mountain is the second of two books in a series marking the beginning of a completely new kind of adventure game. They each contain an exciting adventure program for you to type into your computer. As you play the game on the computer, the imaginary world of the game is vividly recreated in colourful pictures in the book and you can find clues hidden in the pictures to help you.
An adventure game takes you into a different world where you have to pit your wits against magical forces, evil creatures and powerful tyrants. The books give thorough instructions on how to play and hints on what to do if you get stuck.
The programs are written in a standard BASIC and there are conversions listed to make them suitable for the Commodore 64, expanded VIC 20, TRS-80 Colour Computer (32K), Apple II, BBC (32K), Electron and 48K Spectrum.
