Part 1 of an Expert-level quest into a hostile wilderness. This adventure takes place in the Known World of the D&D game, as outlined throughout the D&D game rule books and modules. The DM may find it useful to consult the Companion and Masters Sets, as well as most of the X-series of Expert Set modules. D&D Expert Set module X9, The Savage Coast, would be especially helpful, as Tortles of the Purple Sage could easily serve and continue that module's direction and plot like, adding a previously undescribed area (the Great Northway) to the Known World. The DM may also place the areas and events of this adventure within an existing campaign setting, as long as the geographical areas of the campaign match those set forth here. Pgs. 40-62
