Now this has me thinking what theme songs might fit the major ShadowWorld characters.
The K'ta'viir from the First Era of Ire all seem like they should have 80s music as their theme. Artists like David Bowie, New Order, Romeo Void, and the like. Punk Rock, Post Punk, and New Wave music.
However, Ondoval would fit Black Sabbath's War Pigs pretty well.
