Rooftop Race (Tamir)

Rooftop Race (Tamir) 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 up with another Informant who had no information on Tamir, but suggested that another Informant might do, if Altaïr could reach him in time.

Dialogue
Altaïr met with an Informant on a rooftop in the Poor District. Altaïr raced across the rooftops, and managed to get to the second Informant in time. Altaïr then left to continue his investigation.
 * Informant 1: Safety and peace, Altaïr. I trust you're looking for information to aid you in your strike against Tamir. I fear I've nothing to offer, but Behir might. He shouldn't be too far from here.
 * Informant 2: So, they've sent you, eh? An interesting choice, though not my place to judge. The Rafiq has asked me to observe the souk that Tamir calls home. Here's what I have learned - there's a group of troublemakers, who gather around its south-eastern exit. They and the guards do not get along. Find a way to earn their friendship, and they'll surely be of service to you.

Outcome
Altaïr found out about a group of vigilantes who would aid him, if he managed to gain their trust first.
