High in the Stonecrown Mountains, a new source of dark magic stirs, wakes, and spreads its wings to shroud the land in shadows. The Warlock of the Stonecrowns, an awnshegh regent who is as evil as he is powerful, is draining other regents' sources of magical power, choking their ability to cast the most powerful form of magic of all - realm magic! If that isn't enough, the Warlock threatens to close the only pass connecting the trade-kingdom of Cariele to the rest of Anuire. An army of orogs and ogres is gathering to the Warlock's banner: Are your heroes equal to the challenge of the twisted magic of the Warlock of the Stonecrowns? This open-ended, "adjustable" BIRTHRIGHT adventure is suitable for use with either mid-level (4-6) or high-level (7-10) player characters. TSR 3110
