"The attention to detail and the professionalism of the writing and design is very impressive..." 6/6 from the Wild Die: http://www.wilddie.com/index.php/2018/11/29/game-review-tar-pits-of-the-bone-toilers-by-malrex/
A new trade route is being sought through the Dalgarian Canyonlands¸ pass the friendly Kharazan¸ Village of Plenty. But the last two expeditions have never returned and the merchants are getting anxious for the new route¸ causing bags of gold to exchange hands.
Meanwhile¸ the ancient portal¸ the Maw of Ghormaug¸ has opened once more and invaders¸ ‘bone men'¸ are beginning to take over territory. No one is safe. Left unchecked¸ these lands are destined for horror and ruin¸ unless a brave party steps up to the challenge.
An adventure for Levels 5-8 for Labyrinth Lord¸ Labyrinth Lord Advanced Edition Companion ruleset and other OSR rulesets.
