Yes
Templars are soldiers from the crusades yes. they were in assassins creed because they want power that only the assassin's know about like the "apple of eden"
Yes, in fact there was an 'assassyun's creed back then but it has ended whereas the knights templars still exists.
The Assassins were brave fighters, but they feared the reputation of the Knights Templar. The Assassins gave much money to the Templars in return of safety. In the battle at Sakira, when 5000 Saracens were attacking 400 Assassins, the last ones got saved by 100 Knights Templar. Some legends even tell that Assassins and Templars were friends and the Assassins were Christian.
"May the Father of Understanding Guide [you]."
The Knights Templar really did exist, from 1119 to 1312. They did participate in battles, however, they were not assassins.
By characters, you probably mean templars. Templars are the assassins that Desmond sees in Ezios memory. You will get an assassination contract to assassinate the templar. You can also play as several Templars in the multiplayer of Brotherhood.
Assassinate all 9 of the templars then defeat your master Al Mualim.
The Templars are the opposition to the Assassins. They seek freedom through power and tyranny and will kill the innocent to achieve it. Unlike the Assassins, where they seek freedom through the belief of equality of men. The weapon they choose to use is a Piece of Eden created by the First Civilization that can control the minds of others. However, they cannot seem to find any.
He isn't on any side (he kills british and american templars alike)
well at the end you go on a truck and go to modern day monterigionni
It's actually really complicated but basically, assassins fight templars. The Templars are trying to get their hands on artifacts such as: The apple of eden and the Holy Grail. Basically, they will send these artifacts into orbit and control the human race on the 21/12/12. The day the Mayan calendar ends...
The Assassins. They have been enemies since they split into Templars/Illuminati and Assassins during the crusades but they were defeated by the Assassins and the French at the end of the Third Crusade.
