Malachi Lazuli

So yeah, I think that fits.

The man of sins is a creation of human sins, even if the one who created him isn't.

So, because the creature's body is formed from transformed human remains, and with them concentrated human evil, it can ultimately be destroyed by human virtue?

That would seem to follow.

If you wouldn't mind, I'd like to take a gander at that.

This looks like some kind of preamble to a magical spell or something.

While those of unearthly vice cannot be struck down by any earthly virtue, those fiends of the earth can.

For a pound of purity is worth a cart of corruption.

The parts of nature wherein goodness presides can be harnessed for the purpose of putting down evil distilled from those parts where evil lurks.

Then it goes on to outline some kind of ritual.

The conjuration of the white blade...

But it's incomplete.

Uh, I think you should all see this.

I'm not talking about the storm.

What is it?

Just watch, right over there.

When the lightning flashes, you'll see it, silhouetted.

There!

Did you see it?

Is that... some kind of forest?
