What monster/s are you gonna use if any? Did any jump out at you as must haves? Can any as written get plugged directly into a current campaign?
The Living Dungeon by Christine will definitely see play at my table as will the cloud golem. Both made my mind machines explode with possibilites.
The lightning fey are a tight, clean fit for my Elemental Plane of Air campaign (aboard the good airship "Landkrist" (NO FLOAT STONES PLEASE)). I love those little bastards and their going to be real fun to run when the storm starts tossing the "Landkrist" and an army of lightning bolts descend across its ivory prow.
