That was an awesome take on Sibrand's character. I always was intrigued by him, always felt kind of bad for him. I never saw him that evil, just unstable, driven mad by his fear of death, despair consuming him when his "brothers" were killed one by one and he knew that he could be next. That's something I can hardly judge and that's why I found him to be interesting. I actually always thought he was quite reasonable before his paranoia and you did a great job in describing the change in him. How he realized that there's no God and how that knowledge affected him.
Such a fine piece fanfiction. I really appreciate it how you decided to write about this character. There's definitely not enough fics exploring the Templar side.

Very well written! Very good to see Sibrand's thoughts as to how he became who he was. An excellent story, I hope you write more of Assassins Creed someday.
