Ran Servants of the Cinder Queen today. TPK!
The bad guys got to unleash their plane onto the world. The PCs were fighting skellingtons while squeezing through a narrow fissure and retreating. A cave-in started. They now had room to run, but could not dodge the falling rocks properly (several failed rolls in a row), and they got a very special death scene (after a failed last breath).
Death assured them that there are barmaids in heaven (the fighter had gotten into this adventure to save a kidnapped barmaid that actually had a douchey boyfriend). The god of storms chastised them for failing. The PCs had no children, so their lines ended there and the bad guys took over the area around the mountain.
Some day, maybe a new group of brave souls will be charged with driving them back.
