What is the story to assassin creed trilogy

Assassin's Creed is an award-winning video game series that currently consists of five games, several short films, and a novel. Between the five games, they have made appearances on the iPhone, Microsoft Windows, Nintendo DS, PlayStation 3, PlayStation Portable and Xbox 360 platforms. The two main games in the franchise were developed by Ubisoft Montreal, with the handheld titles developed by Gameloft and Gryphonite Studios, with additional development by Ubisoft Montreal. All games in the franchise are published by Ubisoft.
The main plot arc of the series revolves around a former assassin trainee named Desmond Miles as he is captured by megacorporation Abstergo Industries. Using a device known as the Animus, Desmond is forced to relive his ancestors' memories, who were all assassins, in order to recover artifacts, called the "Pieces of Eden", for Abstergo. While the original assassin ancestor of Desmond was Altaïr, the most recent games feature another assassin from Renaissance Italy named Ezio. Assassination targets are mostly actual historical figures, although the timelines for their lives and causes of death have been changed to suit the games' plot.
The gameplay, varies slightly from game to game, consisting of a mixture of action and adventure, with a heavy emphasis on stealth, in open world recreations of historical cities.




The overarching plot for all of the games takes place in the year 2012. It is implied that the 2012 of the game's timeline is rife with chaos and destruction. In-game emails report of a plague that has wiped out the population of Africa, a story about the Mexican President increasing border security in response to "American Refugees" crossing the border, an extreme amount of hurricanes across the world, and the closing of the last major film studio in an unnamed country.[1]
Amidst this strife, megacorporation Abstergo has devised a plan to seize control of the minds and free will of every person on Earth. To achieve this goal, they must locate artifacts called "Pieces of Eden". Abstergo captures Desmond Miles, a former assassin trainee turned bartender, to search his ancestors' memories stored in his DNA in order to find the Pieces of Eden. Desmond is forced to enter the Animus, a machine that allows for the viewing of such memories.Altaïr's Chronicles
Canonically, the first of Desmond's ancestors' viewed memories take place in Assassin's Creed: Altaïr's Chronicles during 1190, where the Third Crusade is waged in the Holy Land. Altaïr ibn La-Ahad, a medieval assassin, is sent on a mission from the Order of Assassins to retrieve a Chalice from the grasps of both the Crusaders and the Saracens. Altaïr quests to find three different keys then travels to Jerusalem to face the head of the Knights Templar, Basilisk. Upon arriving, he learns that the Chalice is not an object, but a woman named Adha who reveals that Altaïr has been deceived by an assassin named Harash, who is now a double-agent for the Templars. After killing both Harash and Basilisk, Altaïr attempts to save a kidnapped Adha from captivity but is too late. The game ends with Adha sailing away and Altaïr left in Jerusalem.Assassin's Creed
In Assassin's Creed, Altaïr's memories are solicited again by Abstergo in his attempt to find the Piece of Eden. Altaïr, still in Jerusalem, ventures to Solomon's Temple to confront crusader Robert de Sable and retrieve the Piece of Eden for Al Mualim, head of the Assassins. Betraying many tenets of the Creed of the Assassins and failing his mission, Altaïr is demoted to a novice assassin upon return to the Assassin's Fortress. To redeem his previous status, Altaïr is sent by Al Mualim to assassinate nine targets in three different cities. With each kill, Altaïr learns there is a connection between his targets; they are all Templars united by Robert de Sable to take control of the Holy Land by force, although they all claim to pursue a noble goal.
After assassinating eight targets, Altaïr confronts Robert in front of King Richard, leader of the Crusader army. Altaïr informs Richard that Robert is plotting to betray and kill him, which causes him to encourage a duel to the death between Altaïr and Robert. Upon dying, Robert confesses to Altaïr that they were not nine, but ten Templars. The tenth being Al-Mualim, who wanted to keep the Piece of Eden for himself and therefore sent out Altair to kill the others. Back at the Fortress, where Al-Mualim had taken over the minds of the people inside, Altaïr manages to defeat and kill him in a duel. The memory Abstergo was searching for, which located the Piece of Eden, reveals it is only just one of several, the "Apple of Eden", and that over fifteen different other Pieces are scattered across the world.
Back in 2012, Abstergo sends a team to recover as many Pieces as possible. Deciding they don't need him anymore, they give orders to kill Desmond. Lucy Stillman, an Abstergo employee who revealed herself to be an Assassin, convinces them not to kill Desmond until they recover the Pieces, buying him time. Desmond is left alone in the Animus room, and by the use of Eagle Vision inherited, by the 'bleeding effect' of Animus, from Altaïr he sees many symbols drawn on the wall and floor.BloodlinesAssassin's Creed: Bloodlines takes place before the events of Assassin's Creed II but after the events of the original Assassin's Creed. Altaïr has traveled to Cyprus from the Holy Land in order to assassinate the last remnants of the Templars. Here Altair will meet Maria and travel together to kill the remaining templars and learning about the "Apple".Assassin's Creed II
At the beginning of Assassin's Creed II, Lucy returns and breaks Desmond out of Abstergo. He is brought to a hideout and introduced to her Assassin allies Shaun and Rebecca, as well as an updated version of the Animus. Knowing what is at stake, Desmond volunteers to enter the Animus again, and explore the memories of Ezio Auditore da Firenze, a young nobleman from 1476 Florence, Italy.
As a young man, Ezio's father and brothers are executed by the hand of Uberto, a corrupt official in league with the Templars. Ezio kills Uberto in revenge, and after fleeing with his surviving family to their villa in the Tuscan countryside, he learns of his Assassin heritage and begins training under his uncle Mario. Ezio also befriends local inventor Leonardo da Vinci, who helps Ezio with his work by decoding an encrypted codex that contains Altaïr's memoirs, as well as plans for advanced assassin weaponry. Over the course of a decade Ezio assassinates the conspirators involved in his father's death, leaving Rodrigo Borgia, a nobleman and Templar who has retrieved the Apple of Eden and is the center of the conspiracy. Ezio and other Assassins reclaim the Apple of Eden, but Borgia flees. Ezio is formally inducted as an Assassin, and is told that he may be a prophet as described in the codex.
During the course of the game Desmond experiences a number of unusual occurrences. First he discovers strange glyphs apparently left by a previous test subject, similar to the symbols seen at Abstergo, which hide a secret history of the world. He later dreams of appearing as Altaïr again, chasing after Maria, a Templar he had earlier spared, and then romancing her. Finally, several memories are skipped, throwing the timeline forward by more than a decade to the Vatican, where Borgia now resides as Pope Alexander VI.
Borgia has in possession the Papal Staff, another Piece of Eden. He attempts to use it to enter a vault that the prophet as described in the codex must enter. Ezio intercepts Borgia, appears to take his life, and enters the vault himself. He encounters the hologram of a woman, who claims to be once known as the god Minerva, and who also claims to come from a civilization whose members were also seen in the same light by ancient peoples. Minerva reveals of a great disaster that had befallen and destroyed her civilization, and warns that it will occur again soon. Talking directly to Desmond, she tells him "The rest is up to you".
Desmond is pulled out of the Animus as Abstergo has located their hideout. He, Lucy and the rest of the team manage to flee to safety, and soon prepare to return Desmond to the Animus to search for clues that may help them.Discovery
Assassin's Creed II: Discovery takes place during the gap in Ezio's memories which are not explored in Assassin's Creed II. It follows Ezio as he travels to 15th century Spain to free his fellow Assassins, who have been imprisoned under the guise of the Spanish Inquisition. In the process, he discovers that the Knights Templar are planning to sail west to discover the New World.
