Sometimes, there might be other secondary characters that play important roles in relation to 10k and Sarge. For example, characters from their group who might have their own relationships with 10k and Sarge, either as friends, rivals, or something in between. But overall, 10k and Sarge are the central figures that most of the stories revolve around.
Well, obviously 10k and Sarge are the main characters. 10k is known for his unique skills, like his ability to kill a thousand zombies (hence the name 10k). He's often a bit of an underdog but has a lot of heart.
Sarge, on the other hand, is usually more of a tough - as - nails type. He has military experience and leadership skills. He's the kind of character who gives orders and expects them to be followed. In the fanfiction, he might be the one leading 10k and the group into battles or making important decisions.
Another theme could be their growth as characters. 10k might learn important lessons from Sarge, and Sarge could also change his perspective on things because of 10k. Maybe Sarge teaches 10k about combat strategies, and in return, 10k shows Sarge a different way of looking at the younger generation in their post - apocalyptic world.
The Empress herself is of course a main character. Often, you'll also find Space Marines, as they are a significant part of the Warhammer 40k universe and interact with the Empress in various ways. Imperial Guardsmen may also be present, depending on the plot of the fanfiction.
A Vampire Lord from a long - lost dynasty could be a main character. He might be trying to reclaim his former glory in the 40k universe filled with so many powerful factions.
Space Marines can also be main characters. They might be tasked with protecting an STC site or escorting Tech - Priests to retrieve an STC. Their combat skills are crucial in fending off threats.
In Warhammer 50k fanfiction, characters like the Sisters of Battle are quite popular. They are strong, devout warriors, and their stories of faith and combat can be really inspiring. There are also Inquisitors who are often central characters. They have the power to investigate and root out heresy, and their complex personalities, some being more noble and some being more morally ambiguous, make for great storytelling. Additionally, the Ork warbosses can be popular as they bring a lot of chaotic and violent energy to the stories.
Horus Lupercal is a very popular character. His fall from grace and the events leading up to it are often the focus of fanfictions. Another popular one is Magnus the Red. His connection to the warp and his attempts to warn the Emperor make for great story material. Also, Leman Russ is popular. His no - nonsense attitude and his relationship with his legion are often explored in fanfic.
There's Yashiro Isana, who is a key character in the story.
Since I don't know the specific '40k love story', I can't say for sure who the main characters are. They could be anyone from soldiers to civilians in the 40k universe.
Since I don't know the exact 'k seven story', I can't say for sure. But if it's a typical adventure story, there might be a brave protagonist, maybe a character named K or someone related to the 'seven' aspect.
One of the main characters is Ciaphas Cain. He is from the 'Gaunt's Ghosts' series. He is a bit of a reluctant hero, always getting into and out of trouble in the most interesting ways.
