Found some terrible acoustic versions tabbed for this song. This is the correct version.

Chords are:
C
G
F
Am

You can come up with any strumming that fits this, really. I follow the pattern of the
drums starting from the second verse onward, and just play each chord as one long strum
during the first verse into the first chorus to create a nice buildup of the song. All 
up to your playing style.

Intro:
Am  G  F  C
F  G  Am
F  G  C


C                                G
Run through the cold of the night
                  F         C
As passion burns in your heart
C                   G                      Am
Ready to fight, a knife held close by your side
           C                         G
Like a proud wolf alone in the dark
               F                   C
With eyes that watch the world
          C              G                    C
And my name like a shadow on the face of the moon


Am                  G        F        C
Broken mirror, a million shades of light
     F        G                  Am
The old echo fades away
          G    F     C
But just you and I
      F         G          Am
Can find the answer and then
     G       F       C         G
We can run to the end of the world
      F            G
We can run to the end
         C
Of the world


C                        G
Cold fire clenched to my heart
        F        C
In the blue of night
C                        G                   Am
Torn by this pain, I'll paint your name in sound
C
And the girl of the dawn
      G                 F      C
With eyes of blue and angel wings
C                     G            C
The songs of the season are her only crown


Am                  G        F        C
Broken mirror, a million shades of light
     F        G                  Am
The old echo fades away
          G    F     C
But just you and I
      F         G          Am
Can find the answer and then
     G       F       C         G
We can run to the end of the world
      F            G
We can run to the end
         C
Of the world


Am              G   F    C
We met in the mist of morning
        F           G         Am
And parted deep in the night
Am                       G        F        C
Broken sword and shield and tears that never fall
     F         G             Am
But run through the heart
         Am        G  F    C
Washed away by the darkest water
        F          G            C
The world is peaceful and still


Am                  G        F        C
Broken mirror, a million shades of light
     F        G                  Am
The old echo fades away
          G    F     C
But just you and I
      F         G          Am
Can find the answer and then
     G       F       C         G
We can run to the end of the world
      F            G
We can run to the end
      Am
Of the world

F              G
Run to the end
        C
of the world
