[Solved] Company of Heroes for brainy ninjas

Welcome to the third part of my brainy ninja series. Since the second part didn't worked out as expected, i felt the obligation to make a third one.
As before you have to decipher an encrypted key (XXXXX-YYYYY-ZZZZZ), this time it's a key for Company of Heroes.

Here are your hints:

XXXXX:
01:
In the vastness of space,
which I like to embrace,
a bird sings a song,
but he got it all wrong.
01:
I live here all alone,
buried under this stone,
my hair dripping with ink,
while looking at this throne,
which is my antarctic zone,
needing more time to re-think.
01:
The stone finally blooms,
filling more than ten rooms,
hiding closets and fears,
but disaster still looms,
I can smell it fumes,
even after many years.
01:
The bird touches the sky,
flaming arrows arise,
becoming my only ally,
everything has a price.
01:
Hearing thunder and drums,
hearing trumpets and crawls,
getting the last recalls,
tearing down the first walls,
picking up the last crumbs.
10:
I keep sitting still dumb,
painting pictures with coal,
loosing faith on this pole,
knowing I'm out of plumb.
01:
I live here all alone,
buried under this stone,
my hair dripping with ink,
while looking at this throne,
which is my antarctic zone,
needing more time to re-think.
10:
I think I annoyed you enough,
I know this puzzle is tough,
but please give it a try,
ask questions don't be shy,
maybe you'll become a wise guy.

YYYYY
