Lair of the Lamb is an OSR style module by Arnold K. over at Goblin Punch. It's a funnel where players run a total of 12 characters through a dangerous adventure and see who survives to see daylight. Free to use and comes with Arnold's newly updated GLOG version, but can be run with other D&D variants as well. In this case, I used D&D 5e and grounded the place in my Bronze & Sand-"setting".
