It's possible that there is a character who has some sort of special ability or knowledge that is important for the brotherhood. And then there could be a character who is new to the group and has to prove himself to be part of this brotherhood. There could also be an antagonist who tries to break the brotherhood, which would make the relationships between the main characters even more interesting.
Perhaps they are characters from different backgrounds who come together and form this brotherhood. One could be a leader type, strong - willed and decisive. Another might be the more sensitive one who brings an emotional depth to the group. And there could be a character who is the joker of the group, always lightening the mood. But again, this is all speculation without having read the book.
The main theme could be about the strong bond between characters, like a brotherly connection that endures through various challenges and perhaps even death.
In the Dark Brotherhood story, there is often a Listener, who is a key figure in receiving the contracts. And there are assassins within the brotherhood, like the ones who carry out the kills.
Rhage is also important. He has a beast within him, which makes his character both dangerous and endearing. His relationship with Mary is a significant part of the story.
I'm not entirely sure as it's not a very well - known work to me. But it could have a fearless captain as one of the main characters, leading the brotherhood.

Wrath is one of the main characters. He is a strong and powerful leader in the Brotherhood.
I'm not sure specifically as I haven't read the 'death notice novel' in detail. But usually in such novels, there is a protagonist who is likely to be someone involved in solving the mystery or facing the challenges related to the 'death notice'.
The main characters could include the god of death, of course. There might be a human character who has a special connection to the god of death, perhaps a seer or someone with a rare gift. And there could be a council of deities that the god of death has to interact with, whether they are allies or foes. These various characters would each contribute to the overall plot and theme of the novel.
