From the back cover:
"Far-Go is dying...the people are afraid ...the animals are wasting away...the crops are withering in the fields. No one, even Arx Skystone, the high priest, knows what has caused Far-Go's misfortune.
YOU are part of a group of young adventurers about to begin the sacred Rite of Adulthood. The last hope of survival for Far-Go rests with your party. On your journey to the Forest of Knowledge, you must search for clues to the origin of the mysterious plague. This quest may lead you into great danger...and great knowledge. As you travel through the savage wilderness, all you have are your companions, your wits, your strength ...and your dreams!!
