One interesting concept could be a crossover with a fantasy world like Middle - earth. Imagine an assassin having to navigate the perils of Mordor while still maintaining their creed. Another concept might be a crossover with a historical event not directly related to the main Assassin's Creed timeline, such as the sinking of the Titanic, where assassins could be on board for a secret mission.
At the end of the Assassin's Creed series, players will return to the birthplace of the Assassin's Organization, the Italian sea of the Andrea. In the game's final mission, players need to help Alice become her mentor and stop her father, Orion, from becoming the leader of the organization. After completing the mission, the player will sail with Alice and the other members of the Assassin Organization on the sea of Italy to celebrate their success.
Writing a good Assassins Creed crossover fanfic is all about balance. You have to balance the elements of Assassin's Creed, like the hidden blade and the assassin's parkour skills, with the elements of the crossover. Let's say it's a crossover with a detective story. You can't overshadow the detective's investigation skills with the assassin's combat abilities. Also, create believable relationships between the characters. If an assassin teams up with a detective, there should be some initial mistrust that gradually turns into respect and cooperation as they work towards a common goal.
I recommend the following two novels with assassins as the main characters:
1. "Unparalleled Dark Blade" was a fantasy sword and magic novel written by the author, Drunken Dream Nanke. The main character used the true energy of a physician to fuse with the mystic force of telekinesis to achieve a supreme legend. The art of assassination was his life goal.
2. "Assassin Wu Liuqi: Swordsman Lu Jiu" was a light novel by the author, Crayfish and Phoenix Claw. The main characters were Wu Liuqi and Lu Jiu, the shadow assassin and swordsman respectively.
I hope you like this fairy's recommendation. Muah ~😗
The ending of the Legend of the Assassins was not described in detail in the novel, but according to the development of the story, Ah Bao and the Emperor should not be together. In the later part of the novel, Ah Bao chose to leave the emperor and continue to pursue his path as an assassin in order to complete his mission. Although Ah 'Bao had achieved many victories on the road of assassination, he could never forget his family and his original heart. This was also the reason why he chose to leave in the end. Therefore, the ending of the Legend of Assassins should be that after Ah Bao left the Emperor, he continued to be an assassin and fought for his beliefs and mission.
One interesting scenario could be Ezio meeting Altair. Ezio, being from a later era, could learn a great deal from Altair's wisdom. He might be in awe of Altair's original Assassin skills and the way he built the Assassin Brotherhood in the Holy Land. Altair, on the other hand, could see the evolution of the Brotherhood through Ezio and how it has adapted to new challenges in Italy. Another scenario could be Connor meeting Edward Kenway. Connor, who is very much about protecting his land and people, could have an interesting conversation with the more pirate - like Edward. Edward could perhaps tell Connor about his adventures on the high seas and how he came to be an Assassin, which might give Connor a different perspective on the Brotherhood's reach and purpose.
The endings of the main characters in the Assassin's Creed series were as follows:
Arnaud Vestala: Arnaud eventually became a senior member of the Assassin Organization. He and his lover, Amelia, unfortunately died in a mission for the organization.
2 Albaz Vestala: Albaz eventually became a successful assassin. He became one of the leaders of the assassin organization and managed the assassin organization with his lover Sarah.
Alice Fett: Alice eventually became a successful assassin. She and her lover Tom carried out a mission in the headquarters of the Assassin Organization and finally defeated the ruler of the organization, Osiris.
4 Edward Arnold: Edward eventually became a senior member of the Assassin Organization, but his relationship with his wife, Amelia, was very tense. Unfortunately, he died during a mission for the organization.
5. Connor Radcliffe: Connor eventually became a successful assassin. He unfortunately sacrificed himself in a mission to protect his lover Sarah.
6 Tom Clancy: Tom eventually became a senior member of an assassin organization. His relationship with his lover, Amelia, was very stable. Unfortunately, he died during a mission for the organization.
The protagonists of the Assassin's Creed series had tragic endings because they had experienced many difficult missions and painful feelings. However, the victory of the assassin organization did not mean that their ending was perfect, because some of them were eventually revealed as hypocrites while others became heroes.
I think the ending is good. It gives a sense of closure to the main events and character arcs in the game. However, it also leaves some room for interpretation, which I like.
