The theme of their origin and backstory is also quite common. Since the official lore doesn't have female primarchs in the same way as male ones, fanfictions often create their own backstories for these characters. This could involve how they were created, their early experiences, and how they came to be the powerful entities they are in the fanfiction's narrative. This gives the writers a chance to add their own unique twists to the Warhammer 40k lore.
No. Although they are deeply rooted in the Warhammer 40K lore, the primarch novels can be appealing to a wider audience. The character development of the primarchs is quite detailed. For example, the story of how a primarch rises or falls can be interesting even to those who are not die - hard Warhammer 40K fans. There are elements of politics, war, and personal struggle that can engage readers outside of the core fanbase.
There might be a fanfiction where a Primarch is reborn in a different era of the Warhammer 40k universe. In this story, they have to adapt to the new circumstances, which are very different from what they knew. They might find that the Imperium has changed in ways they can't fathom, and they have to fight new enemies and face new politics within the Imperium.
Magnus the Red is also an interesting choice. Given his connection to the warp and his fall from grace, there are many stories that can be told. Maybe a fanfiction where he tries to redeem himself in some way, or a story that delves deeper into his relationship with his father, the Emperor, before his downfall.
The Primarch Horus is often a very popular character. His fall from grace and the events leading up to it are a major part of the Warhammer 40k lore, and in fanfiction, there are many interpretations of his motives and actions. Another popular one could be Magnus the Red, with his powerful psychic abilities and the complex relationship he has with the Emperor and his fellow primarchs.
In this type of fanfiction, the main characters associated with the 11th Primarch can vary widely. There could be Inquisitors who are either investigating the 11th Primarch or working with him. These Inquisitors could bring their own motives and agendas. Tech - Priests might also be important characters as they could be interested in any new technology or knowledge that the 11th Primarch might possess. And of course, there could be Chaos Lords who see the 11th Primarch as a threat or an opportunity for their own dark purposes.
You can start by looking on fanfiction websites like Archive of Our Own (AO3). There are often many Warhammer 40k fanfictions there, and you can filter for those specifically about female primarchs. Another option is to check out some Warhammer 40k fan forums. Fans often share and discuss their favorite fanfictions on these forums, and you might be able to find some great ones about female primarchs that way.
Well, in Warhammer 40k 2nd primarch fanfiction, a cool concept is the power dynamics. The primarchs are incredibly powerful beings, and seeing how they interact with other powerful entities in the universe, like the Chaos Gods or the Emperor in different scenarios, can be really engaging. It can also show how their individual personalities shape their actions and decisions.
Another interesting concept is to have a Primarch face a completely new enemy. Not the usual chaos forces or xenos, but something from within the Imperium itself that has turned against it. This would create a lot of internal conflict and moral dilemmas for the Primarch to deal with.
Well, in the fanfiction, perhaps the 11th Primarch has a distinct relationship with the Chaos forces. Unlike other Primarchs, they might have a more nuanced view towards Chaos, not entirely good or bad. This could lead to some really complex and engaging storylines. Another aspect could be their influence on the different factions in the Warhammer 40k world. For example, how they affect the Imperium or the xenos races.
