Yes, that was my intent. Skulls everywhere ….who knows, why there are so much of them.

There is a magic circle in the middle of the ground. Somebody conjure up the devil, maybe the deepling or was it somebody else?

What is it, what the one wanted and did. Did he had problems with a group of people and wanted the devil to kill them in excange for his soul.
Or he wanted more power and gave in exchange the souls of many others.
But it also could be, that he wanted to avenge all the people, who were killed by this devil.

There are a lot of possibilities
