Kingdom - road to Damascus
Status: Speak with the Bureau Leader in Damascus.
To reach the city you need to find a horse. It's behind the palisade. Leave Masyaf and you will find yourself in the Kingdom. You can find Damascus on your map - the rest of your map will appear when you synchronize towers on your way. Find the first one, climb to the top and synchronize. Now everything should be clear.
On the crossroads turn left. After a while, you will end up in a village where you can find a tower. Move southeast. When you're being chased, you can always hide in the haystack. Before you reach the city, you should synchronize two more towers.
Damascus - investigation
Status:0/6 Investigations Complete. 2 Investigations are needed to access Assassination Memory. Climb view point to locate them.
The gate is strictly guarded so you must find another way. Save the citizen and go to the city with a little help from the scholars. Now look at your map and find the synchronization point. Climb onto the tower, synchronize and go to the Bureau (marked as A on your map). Now get to the rest of synchronization points to get all tasks needed for investigation.
On the map above you can find all investigation tasks you need. But for now you just need two of them. Most of the information is useless but you can collect all of it if you like.
1. Pickpocket. In the stolen letter, there is information about some kind of supply planned by Tamir.
2. You will find you can get to the marketplace using roofs in the northeastern part of the district.
3. You will find out that Tamir ordered a meeting.
4.Eavesdropping. You will find out that you can penetrate Tamir's surroundings using wooden beams.
5.Interrogation. Your victim will tell you that Tamir is supplying weapons not to Saladin but to some other recipient.
6.Eavesdropping. A dialogue leads to a conclusion that it's good to have at your disposal men who can distract soldiers during a chase.
After you get an order to kill Tamir, go to the place marked on your map. Prepare the hidden blade and when Tamir goes close to the merchant slowly walk behind him and assassinate him. Now escape as fast as possible to the Bureau.
Attack Tamir with your hidden blade
You're in the lab again. Speak with the girl; you can also read some e-mails but overall, there's not much to do here. Go to sleep and after waking up go back to your work.
