Talos is one of the main characters. He's a complex figure, often conflicted between his loyalty to the Night Lords and his own sense of morality. Another is Sevatar, a powerful and feared leader within the legion.
One great one to start with could be 'Soul Hunter'. It really delves into the dark and brutal nature of the Night Lords. It gives you a good sense of their culture and how they operate within the Warhammer 40K universe.
The characters are very interesting. You have these complex individuals within the Night Lords. They are not just one - dimensional bad guys. They have their own motives, their own stories of how they came to be part of this terrifying legion. And the novels do a great job of bringing these characters to life, making you care about them even though they are on the 'evil' side.
Well, there's also the theme of the fall from grace. They were once part of the Emperor's grand plan but have deviated so far. This is shown through their actions and the way they interact with the rest of the 40k universe. Their once - noble purpose has been warped by their experiences and choices, which is a central exploration in the novels.
The 'Eisenhorn' trilogy is also among the best. It focuses on the Inquisitor Eisenhorn as he battles against the various threats to the Imperium, from Chaos cults to alien infiltrations. It's a great read for those interested in the Inquisition and its workings in the 40k setting.
Some of the best W40K novels include 'Horus Rising' by Dan Abnett. It really sets the stage for the Horus Heresy saga, introducing key characters and the events that lead to the great betrayal. Another great one is 'Gaunt's Ghosts' series which follows Colonel - Commissar Ibram Gaunt and his Tanith First and Only regiment through various battles and campaigns in the grim darkness of the 40K universe.
I think 'The First Heretic' is very popular. It has a complex plot that involves the fall of the Night Lords legion from their original state. It also has great character development for the main characters within the Night Lords.
Sure. 'Fulgrim' is a great one. It delves deep into the fall of the primarch Fulgrim and his legion, the Emperor's Children. It shows how the allure of Chaos can corrupt even the mightiest of the Imperium's heroes.
Most literature is centered around human relationships, emotions, and experiences that are within the boundaries of propriety. A story with a 'pervert wife' and a K9 is not something that has been given much attention in the literary canon. It's not a theme that would be promoted or celebrated in the world of books and stories.
