Stealth Assassination (Sibrand)

Stealth Assassination (Sibrand) was a virtual representation of one of Altaïr Ibn-La'Ahad's genetic memories, relived by Desmond Miles in 2012 through the Animus.

Description
Altaïr met with an Informant who offered to share his knowledge, in exchange for eliminating several Knights Teutonic.

Dialogue
Altaïr approached the Informant in an alley. Altaïr assassinated all the targets, and returned to the Informant.
 * Informant: Did they let you into the city, or did you fight your way in? Ohh... Perhaps I should be more respectful, as I myself now require your help. I spent too much time in the harbor brothel last night, and insulted a Teutonic Knight's wife, or so I am told. Now there's a group of them after me. Could you give me a hand, or a blade? If you return before I leave the city, I will give you the benefit of my wisdom.
 * Informant: You are a lucky man, you are alive and I am still in Acre. Here is what I have to tell you - the only thing more dangerous than a drunken sailor is one who is also angry. I know it does not seem like much, but with your wisdom I am sure it will help.

Outcome
Altaïr learned that many drunk sailors populated the docks.
