TLDR: Which linked song do you think is the best for a theme song? Or do you have another suggestion?

So, I had the thought of adding a theme song to a D&D world I've been creating, and i'd like some help deciding and/or suggestions. It's inspiration was largely the idea of not being stupid with their magic, since the characters in most of them absolutely are (being smart tends to close off possible plotlines).

The Mile-High-View of the world's history is that the material plane used to be entirely dominated by a tyrannical nation that was overthrown a couple of hundred years ago. Upon the overthrow of that nation, the victors learned of a massive threat to the plane that said nation had been preparing for (I haven't yet decided what that will be yet, but it'd be Extinction-Level); probably some kind of multi-planar war/attack.

The new nations formed their society around more warrior-like codes of honor. Enforcing strict societal standards of self-sacrifice, hard work, honesty, and self-reliance as well as universal military service. All of which were aimed at preparing for this threat.

Now, a couple centuries later, the threat is almost here and society falters. And religious leaders, cultural leaders, governmental leaders are struggling to reignite the societal ties that will bind the material plane together to stand against the threat before it's too late, which it might already be.

The nations fracture, the end of the material plane is already beginning.... and I'm trying to find a song that conveys this or fits this. I'm a fan of Audiomachine for theme songs, and I've narrowed down to a few that I'll link here. Which do you think fits best? Or do you have a suggestion? I'm leaning heavily toward I Fear Nothing (linked), but i'd like other votes as well.
