I actually listened to a lot of music when i created Cyrgon and I quite often chose different music depending on which kind of character I was playing at the moment.
I think if my memory doesn't fail me, the original intention of the character was sort of a blend of the following;
Amon Amarth - For the stabwounds in our backs
Deathstars - The Rape of Virtue
At The Gates - Cold
Siebenb
