I released a Labyrinth Lord compatible adventure called The Curse of Cragbridge over at RPGNow and DriveThru RPG. Currently, the book is PDF only, and Pay What You Want. From proceeds, I plan to do a digest-sized print edition (if there's interest) with updated art and maps. Additionally, if interest is there, I plan to go level-by-level into the Sunken City of Xerichen and its Prisons of the Demigods. Stay tuned for conversion information for other game systems!
Here's the blurb:
Prison of Sprits Betrayed!
A Labyrinth Lord compatible Adventure for Characters level 1-3.
For five hundred years, Cragbridge has stood abandoned and cursed. Within lurk the haunts and spirits of those that served Lord and Lady Etheril. Some of these ghosts inhabit the forms of strange insect creatures, while others guard tombs deep beneath the shattered bridge tower.
Recently, the good knight Sir Dougal Skavok disappeared in the ruins, and when the search party returned, they too were missing a few members. But, they carried strange treasures found there: coins marked with a double-headed raven, gemstones of great value, and other ornate and gilded items. They also spoke of the curses and haunts that lurk under the ruins of Cragbridge!
Featuring all original monsters, two unique magic items and a hell of a lot of fun.
This purchase includes three PDF versions: a standard pdf, a "two-up" pdf with two pages per printed page, and a booklet format pdf.
So, if you like Labyrinth Lord and you like creepy haunted towers, and you LOVE Pay What You Want, trip on over to RPGNow or DriveThruRPG and pick them up.
While you're there, pick up +Daniel Bishop's PWYW Labyrinth Lord mega-dungeon starter (I swear we didn't plan this): The Dungeon of Crows.
