A desperate mission sends the rangers deep into the trackless desert north of Alladore. Somewhere in that wasteland is a hidden entrance to the Shadow Deep, an entrance that could prove the only chance for a daring rescue… This book is the first of three that together make up a single mission called ‘The Rescue’. It includes 4 new scenarios designed for rangers of level 10 and above, as well as a pair of unique companions, and a host of fearsome new monsters. The book also includes a section on Advanced Herbalism that greatly increases the number of herbs that are available to rangers and gives new rules for using them and searching for them during missions. —description from the publisher
