Well, Kassandra is a really cool and complex character. Her story in the game is so rich that it leaves a lot of room for fanfiction. People are drawn to explore her further, like her relationships with other characters or what she does after the main game events.
Power and its consequences is a frequent theme. Given Kassandra's abilities in the game, fanfictions might explore how she uses or misuses her power. Also, friendship and loyalty are common. She forms bonds with various characters in the game, and in fanfiction, these relationships are often deepened or tested. For example, her relationship with Barnabas is often a central focus in many stories.
One idea could be a story where Kassandra, during one of her adventures, stumbles upon a mysterious portal that leads her to the Underworld. There, she meets Hades. Hades is initially suspicious of her but soon realizes she has no ill intent. They could form an unlikely alliance to deal with a threat that endangers both the mortal world and the Underworld.
Another interesting one is 'Kassandra, Champion of the Creed'. In this fanfiction, Kassandra becomes a central figure in the Assassin's Creed organization much earlier than in the main storyline. It's full of action and shows her making important decisions for the Creed.
There are quite a few out there. For example, 'Kassandra's Redemption' is a fanfiction that focuses on Kassandra's internal struggle with her past actions. It gives a deeper look into her character. Also, 'Kassandra and the Mysterious Artifact' is exciting as it has her on a quest to discover the power of a long - lost artifact. This one has a lot of action and mystery elements.
A good plot twist could be that Hades was actually being controlled by an ancient evil force all along. Kassandra discovers this when she notices his strange behavior. She has to find a way to break the control and save Hades as well as the Underworld from this hidden threat.
Assassin's Creed 2 was a novel by the British author, Asimoff, which was first published in 1984. The novel mainly tells the story of the protagonists Arnaud Verstapp and Alice Fisher on a mission in Paris in the early 20th century. In the novel, Arnold and Alice became an assassin and a templar respectively. They had to protect the safety of the citizens of Paris in various crises.
Assassin's Creed 2 is a fictional story written by George Miller and John Carmack, first published in 1992. The story takes place in the late 18th century in England. It tells the story of an assassin named Alice fitzgerald who embarked on a dangerous mission to save her family.
In the story, Alice was sent to London on a mission to protect a member of the royal family from an assassin. However, her mission did not go smoothly because the leader of the Assassins, Beryl Wendney, had already obtained a map of London and planned to use this opportunity to launch an attack. Alice had to make a decision in Wendney's plan and find a way to stop it.
In addition to Alice's story, the novel also deals with political conspiracy, love, betrayal, and violence.
Assassin's Creed's recommended novels were Assassin's Supreme and Assassin's Night League. These two novels were about how the peak assassins who descended to the other world demonstrated their own path of assassination, and the story of the assassins who had a reward of one billion dragon coins fighting for the revival of the Assassin Alliance. In addition, there were other Assassin's Creed novels, such as Assassin's Creed: Revelation, Assassin's Creed: Abandoned, Assassin's Creed: Brotherhood, and so on. These novels presented the world of Assassin's Creed with different backgrounds and storylines.
It's not appropriate at all. The 'Assassin's Creed' brand has been built on elements like assassinations, historical mysteries, and parkour in beautifully recreated historical settings. Adding sexual fanfiction would be a deviation from what makes the series great and would also be unacceptable in a general entertainment context.
