The Archdemon had been defeated, and a semblance of peace returned to Ferelden. King Alistair married Elissa Cousland, and together they worked to rebuild the kingdom. The elves in the Alienage got more of a voice at court, and King Alistair even appointed one of them, a very outspoken young woman, to his court.
Who was the one to give their life to slay the archdemon? None other than Teyrn Loghain, conscripted into the Grey Wardens for his part in the crimes against the Grey Wardens, and Ferelden as a whole, at the Battle of Ostagar. It is said that he redeemed himself in his sacrifice.
Six months after the archdemon's defeat, roving bands of darkspawn began to emerge. Intelligent, talking darkspawn lead them. This matter was swiftly taken care of by Warden-Commander Elissa, Arl of Amaranthine.
Just a year after the discovery of the talking darkspawn, Lady Elissa was discovered to be with child, a miracle in itself since both herself and King Alistair were tainted as Grey Wardens. The child, a girl, was born healthy, in 9:34 Dragon, with only one problem. She had no voice. But this did not worry them. They named their daughter Eleanor, after the late Teyrna, and she was named heiress, as King Alistair's firstborn child.
Thus, life returned to a semblance of normalcy for the royal family. Of course, normal only lasts so long.
But Ferelden was not the only great nation affected by the darkspawn. The second child of the late King Endrin Aeducan, the Princess Sereda, was given her rightful place as queen after her rights were restored once her younger brother Prince Bhelen's treachery was brought to light by Lord Harrowmont. However, Queen Sereda requested that Bhelen's remains be left in the Aeducan burial chamber, and not three days later a single sentence appeared, carved into the stone near where Bhelen rested. You will always be my brother. This same sentence was found carved into the wall near where Endrin's eldest, Prince Trian rested. It is believed that these are Lady Sereda's doing, but no one knows for sure.
Since taking over for Lord Harrowmont, Queen Sereda has started implementing things she claims were her brother Bhelen's plans. However, she believes them to be the best for Orzamar. And with help from fellow Grey Warden, King Alistair, the Aeduchan Thaig has been reclaimed at last.
Queen Sereda was named Paragon by the Assembly for her part in the defeat of the archdemon, and a new house founded bearing her name. It was then that she wed to a man of the Warrior caste, who she had loved for years, who's wife had died in the darkspawn attack on Denerim. Gorim and his daughter were accepted into House Sereda, and together Gorim and Sereda had another child, a son, that they named Endrin, after Sereda's father.
With a Grey Warden each from the Alienage and the Dalish Clans, the lot of the elves improved. The Alienage's Grey Warden, an outspoken woman named Kallian, convinced King Alistair to put her cousin Shianni on the council.
The Dalish Grey Warden, a young man by the name of Theron, returned to his Clan a year or so after the archdemon's defeat. The only thing Warden-Commander Elissa gets from this Grey Warden is the occasional letter reminding her that she only need call, and he will return to fight.
The Warden mage was an elven woman named Neria, who proved to the Templars that the Circle deserved a chance to watch their own, without interference. King Alistair granted the Circle autonomy because of Neria's actions. Unlike the other Grey Wardens, Neria was killed in the final assault on Denerim by one of the archdemon's generals. She took him down with her, and was honored for it. A new Circle was built to replace the old one, where the Veil was too thin now for so many mages, and it bore Neria's name. She became known as the hero of the mages, granting them the freedom many of them had desired.
