From publisher blurb:
What is the Darkenfold?
The Darkenfold is a forest set in the world of Aihrde, the official campaign setting for C&C. It is ripe for adventure. It is also home to 5 published adventures and the preferred area of play for Stephen Chenault, of Castles & Crusades and World of Aihrde fame, in his home game as well at conventions and pick-up games.
The Darkenfold holds more significance than that however, for in many respects it launched Troll Lord Games the company with the adventure module C1 The Mortality of Green. The adventure was originally written in the early 1980s and submitted to TSR for publication consideration. The esteemed Roger Moore mad notations on the book and returned it to Steve. Years later it became the cornerstone adventure that Mac Golden (founding member of TLG) and Steve used to launch the company.
Later it was was followed up by a bevy of other adventures C2 Shades of Mist, C3 Upon the Powder River, C4 Harvest of Oaths and C5 Falls the Divide. All these adventures take place beneath the eaves of the forest.
