Guess the song

I'm alone here on my island Floating in the sky, I'm High above the world I used to know And I'm far from any danger Safe from any failure Guarded, I found shelter in the storm I'm hiding in the blue Safe between the clouds In the blue Where I can't be found Was a soldier in the legions Fought against the demons Fought against the monsters made of gold But they stormed across Arcadia Following their nature Washed away the place I once called home
