Easy song, the chords throughout are simply:

D - Em - Bm - G

The first minute of the song has some heavy synth. If you've got 
an eBow or some similar sustain pedal/reverb, you can play on:

    D   Em   Bm   G
e | -------------------- | 
B | -------------------- | 
G | -------------------- | 
D | -14~--16~--11~--9~~- | 
A | -------------------- | 
E | -------------------- | 

The rhythm is a slight bit "weird," so I tried to show the chords over
the appropriate parts of the verses. Just listen to the progression to 
find the exact timing...

D    Em    Bm      G              D
           I'm the king of my own land,

D             Em          Bm         G               D
       Facing tempests of dust, I'll fight until the end,

D                             Em           Bm            G      D
       Creatures of my dreams raise up and dance with me!

D       Em    Bm            G       D
Now and forever... I'm your kiiiiiiing!

D - Em - Bm - G (etc...)
