One idea could be exploring Yorshka's origin in more depth. Maybe she has a hidden past that involves a powerful being from another realm. Another plot could revolve around her relationship with the player character. For example, they form an unexpected alliance to face a common threat in the Dark Souls 3 world. A third plot idea could be that Yorshka discovers a long - lost power within herself that changes the balance of power in the game's universe.
A possible plot idea is Yorshka getting lost in a strange part of the Dark Souls 3 world. The player character has to guide her back while protecting her from various enemies. Or, perhaps there's a fanfiction where Yorshka is cursed and the player has to find a way to break the curse. Another interesting idea is that Yorshka dreams of a different world and the fanfiction follows her journey to try and make that dream a reality within the context of the Dark Souls 3 setting.
The player character is an obvious choice. Their interactions can be very interesting as they come from different backgrounds within the Dark Souls 3 lore. Another good character to pair with Yorshka could be the Fire Keeper. They both have a certain ethereal quality and their combined knowledge could lead to some great storylines. Also, the Emerald Herald might be a good pairing. Her wisdom and Yorshka's unique nature could create a dynamic where they help each other in different ways.
A possible plot could involve an OC who is a healer with a mysterious past. They find themselves in the middle of the Dark Souls' dark and dangerous world. They start out trying to simply survive but soon realize that they have a greater purpose. Their healing powers attract both the good and the bad, and they must decide who to trust as they navigate through the complex politics and battles of the game's world.
One plot idea could be the Fire Keeper's journey to discover her true origin. Maybe she starts having strange dreams that lead her to explore forgotten areas of the game's world. Another could be a love story between the Fire Keeper and an unnamed warrior. They meet during the warrior's journey to link the fire and gradually fall in love, but their love is tested by the harsh realities of the Dark Souls universe. A third idea is that the Fire Keeper gains the ability to see the future and tries to change the fate of the world, which goes against the natural order of things in Dark Souls 3.
One idea could be that the characters from RWBY are transported into the Dark Souls universe. They have to adapt to the harsh and unforgiving world, facing the difficult enemies and complex level designs. For example, Ruby could use her scythe skills in the Dark Souls combat system, but find that the enemies are much more resilient than the Grimm she's used to.
One idea could be exploring the origin of the Age of Fire from the perspective of an unknown character. Maybe a commoner who witnesses the first spark of the Age of Fire and their journey to understand its significance.
One plot idea could be exploring Priscilla's origin in more depth. Maybe she has a hidden past that involves other powerful beings in the Dark Souls universe. Another idea is a story where a character befriends Priscilla and tries to protect her from those who would harm her for her unique nature. A third could be a time - travel fanfiction where a character goes back in time to prevent Priscilla's isolation in the painting world.
You could write a fan fiction about a group of survivors in Lothric who are trying to find a way to escape the cycle of fire and death. They could discover ancient secrets about the world that the main characters in the game don't know. This group could include characters from different classes and backgrounds, like a pyromancer, a cleric, and a rogue. Their interactions and the different skills they bring to the table would make for an interesting story as they navigate the dangerous world of Dark Souls 3.
One idea could be a crossover with 'The Lord of the Rings'. Picture the Dark Souls characters in Middle - earth, facing off against orcs and other dark creatures. Another could be a crossover with 'Bloodborne'. The gothic and nightmarish settings of both could blend well, with hunters and Dark Souls' warriors teaming up against a greater evil. A third idea might be a crossover with 'Final Fantasy'. The different magic systems and character classes could create really unique and exciting storylines.
A crossover with 'Final Fantasy' would be cool. The magic systems in both could be combined in interesting ways. For example, a Dark Souls 2 mage could learn some spells from a Final Fantasy character. Also, a crossover with 'The Elder Scrolls' series. The vast open worlds of both could create an amazing setting for the fanfiction. The character could explore different regions of Tamriel and use their Dark Souls 2 abilities to survive.
One plot idea could be that the Fire Keeper from Dark Souls is transported to another world in the crossover. There, she has to adapt to new rules and powers. Maybe she meets characters from the other universe who initially mistake her for something else due to her unique appearance and abilities from Dark Souls. Another idea is that she teams up with a character from the crossover world to fight a common enemy that threatens both of their realms. This enemy could be a powerful being that feeds on the essence of different worlds, and their combined knowledge and skills are the only hope to stop it.
