Maybe it's connected to this ominous "Gate of the Underworld".

If Atlas Flame founded this village at exactly this point, he might have used himself to block off this gate and that's why Silver mistakenly believed that feeling of demonic magic came from Atlas himself, rather than from the gate beneath/close to him.

First the Underworld was barred off by Atlas Flame, then it was barred off by the magic ice and when Gray made a hole in the ice, Doriarte said that the gate opened. With both the Dragon's spirit and the ice gone, the gate could be open again.

And we still have no idea why Succubus Eye was there in the first place. Were they trying to undo the freezing spell? Were they trying to steal the Eternal Flame? Or might they have been after Silver (whether for a friendly meeting or a confrontation)?

So many question!
