With the recent developments.. Have to say;
For Amendez: Drowning Pool - Duet
For Yammael (My lovely Warlock): Machines of Loving Grace - Golgotha Tenement Blues
For Azaviel (My Priest): Porcupine Tree - Halo
For Corpue (My Warrior): Children of Bodom - In Your Face
Hate it or love it, but you cannot deny: this music fits perfectly to Death Knights. I saw them live last year and the whole atmosphere was so dark and evil <3
For some reason I see certain type of Classical to be a more of a fit.. Try Epica.
The list of my chars and what i see as their themes
Goldseeker - Iron Maiden - El Dorado
Bloodswash - Alestorm - Of Treasure
Katarina - Cynthia Harrel - I Am The Wind
Girdwood - Metallica - Of Wolf and Man
0:00-0:15 would be what he seems to be on the outside.
