The Dragon Age Series is set in the realm of Thedas. The world has a rich history of conquest and magic. The name Dragon Age is in reference to the return of the dragons to the world. They had previously been believed to be extinct, largely by Nevarran dragon hunters. The main evil force throughout the series are the Darkspawn, as well as there Archdemon overlords. Long ago, during the reign of the Tevinter Imperium the most powerful tevinter magisters travelled deep into the heart of the fade (the realm of dreams, magic, and demons). The heart of the fade once held the golden city, seat of the maker (the humans' god figure), when the magisters attempted to usurp the city it blackened. Their bodies became twisted and they were cast back to the world as the first Darkspawn.
When the darkspawn find an Archdemon (old gods corrupted by the darkspawn in the form of dragons) a blight begins. The archdemon leads a horde of darkspawn to the surface to pillage and defile the land.
This is where the Grey Wardens come in. Men and women from every race and class that have made a vow to protect the world from darkspawn. The Grey Wardens are not only bound to the darkspawn by vow, they also are bound by blood. Grey Wardens drink the blood of their enemy to gain there strength. It allows them to defeat archdemons and sense the darkspawn. Sadly, darkspawn blood is poison and many do not survive the Joining (ritual in which the blood is drank). Those who do survive will have shortened lifespans.
At the start of the Dragon Age there has not been a blight for 400 years, so the Grey Wardens are few and, in many places, hated.
Official DescriptionYou are a Grey Warden, one of the last of a legendary order of guardians. With the return of an ancient foe and the kingdom engulfed in civil war, you have been chosen by fate to unite the shattered lands and slay an archdemon once and for all. Start your adventure by picking your race as a Human, Elf, or Dwarf, then your class as a Warrior, Mage, or Rogue. Then after that, it is all up to you. The choices you make guide the path you take through the Ninth Age: The Dragon Age. That is the story line for the first Dragon Age.
PlotThe player character—"the Warden"— is a new grey warden recruit within Ferelden, and begins his/her journey to halt the inevitable blight as one of the six origin stories. The origin chosen determines who the Warden is prior to the main events of the game's story. By the same measure, it also affects how NPCs (party and non-party) will react to the Warden. Elves, for example, are often viewed as second-class citizens. The last warden will be given the task of building an army to match the blight and gather companions along the way to support him/her on this onerous task. As the last grey warden within Ferelden, the actions taken, both indirectly and directly, will decide over the course of one year, which factions align with the warden to build this army and halt the blight, as well as the fate of those met on your journey.
OverviewThe events of Awakening begin six months after the conclusion of Dragon Age: Origins. The player takes on the role of a Grey Warden commander, who is either an imported character from Origins or a new Warden from Orlais. The Orlesian Warden is treated differently because of the history between Orlais and Ferelden—and because an imported Warden will be renowned to begin with, having killed an archdemon almost single-handedly in Origins.
While rebuilding the Grey Wardens and establishing Vigil's Keep, a fortress given to the Grey Wardens at the end of Origins, as a new base of operations, the Warden is faced with a new challenge. It is revealed that despite the defeat of the archdemon, the darkspawn have not returned underground and a new variety of sapient, speaking darkspawn have been discovered. Two entities, named The Architect and The Mother, appear to be involved and the Warden may have to deal with them. Once this mission is complete, the world will have changed dramatically.
PlotSpanning over a decade, Dragon Age II determines Hawke's actions in the political chaos of Kirkwall, their rise to power. Hawke escapes Lothering under the threat of the Blight with his/ her family to the Free Marches and eventually becomes an important character in Thedas as the Champion of Kirkwall. Hawke is involved in a course of actions that will change the world forever. Cassandra Pentaghast, a Seeker of the Chantry, is interrogating Hawke's dwarven friend Varric Tethras in hope of finding the Champion whose aid Cassandra is searching for in her quest to reverse the change. Varric tells Cassandra Hawke's whole story as he is unaware of Hawke's current location.
In Dragon Age 2 you are able to import your Origins save, similar to the Mass Effect series, and it will scan the save for key plot events, which will effect some of the plot elements in the game. But you do not play the same character.
