Gods tend to inhabit objects representing them. Is from worship by followers, enables them to do it.

You could be correct about it being of religious purposes. It could hold...a slumbering deity within. Nobody would know unless it made itself known.

[Because that's how it works in his world, at least, gods can be anywhere. Ganesh is inhabiting a statue his devout followers made, and there's an ancestral hyena god underground pretty close to where Ed lives]
