Hello, i was very happy to find a website like this, where i can share my ideas for future games and characters. I havent played early games but i learned the story through searching.
In this topic i would like to suggest a different kind of Assassin. The idea will be very similar to Rogue yet totally different in terms of motives.
Through the games so far, we have seen many kinds or Assassins. Serious ones like Connor, Freedom fighter like Adewale, gang creating Jacob. And we have also seen Assassin's turning Templars like Shay. Haytham was in Order since early ages however he might fit into this.
Yet one thing i never saw in an Assassin and thought it would be amazing to have a character with it was : Mental Disorder
I imagined an Assassin, going insane because of a certain experience, or maybe having the issue since birth. He gets thrown out from Brotherhood and is haunted down. He sees things that do not exist or he confuses who the enemy was. Confusing who is the enemy and who is the friend is very important as it would demonstrate the similarity of Order and Creed. This character would kill both sides thinking they are both wrong. Through his arc he would kill many friends accidently, but at the end of it, he will be healed of his mental illness and kills himself for the things he has done. Or maybe he decides to become a Hunter like Shay but he hunts both Assassins and Templars, thinking their fight over the ancient weapons and their involvement in history is killing everything.
It might not need a mentally unstable character to question those things however in my opinion having one would make it much more interesting. I wanted to share this here, it was in my mind for a long time.
