Ran this for two players using Cairn 2e! Great simple adventure location. The treasure tables for almost every space was super helpful for my players to search around and good fodder for storytelling. They engaged with the broodlings, fought the Wyrm, got treasure, and got out of dodge!
The hook I used was that they were condemned slaves brought to the Maw to appease the Wyrm. Their slaver told them, "Die, that's fine. Get enough loot to pay off your debts, better. Kill the Wyrm? Best."
The map was good as well since it included what I interpreted as cave squeezes. Made a lot of interesting choices for the characters in how to manage their inventory and navigate. 7/10, would use it again.
