Gentoons

Ok, here's the whole series in one post. "Conclave of Corpses," or "The Monk of Horror" by Anonymous. In a monastery high in the Piedmonts, a brotherhood of monks lives their peaceful existence....until one night:

The monk awakens in the night. What has he heard?
The Monk Is Drawn to the Old ChurchThe monk stumbles down the old stone stairs into the crypt.

He is confronted by the fearsome triumvirate...

Which sits guard over the bodies of all the monks from ages gone by. A rift in the floor opens up, skeletons and mouldering corpses clamber out, shrieking their unending death agonies. (anyone for a nice kitty cartoon now?)
The monk awakens the next morning in front of the church, and behaves himself the rest of his life. The end.
