Now who doesn't want to root around in and under the Middens and the sewers beneath them? You don't? What about your player characters?
This adventure will require some changes to play well with Ptolus, but the concept is solid.
Evil Locathah, non-evil Locathah, lot's of nasty encounters and dangerous filth. What's not to love?
Diseases are at the root of this adventure. Included in the scenario are 6 new diseases, described in juicy detail.
The evil Locathah are worshippers of a god of disease and have chosen the midden and the sewers and caves below to set up a lab for incubating more and more virulent disease strains.
You may have to put some effort toward getting the player characters involved in this mess, but a couple of options are put forward. A missing friend is one possibility, but I like the second option better because it can be developed with more detail. An important item, maybe a family heirloom has been accidently dumped into the vastness of the Midden and because of its nature the owner is willing to pay for delvers to go and get it back. There are also some missing people being held down below so the PCs might be pursuing that lead.
You can easily combine this with other scenarios like the one with Ularis Gadare offering a reward to go in and retrieve something he wants.
