The tale of Aedan Cousland, a warrior of exceptional skill tempered by a diplomatic mind, ended when he sank the blade into the archdemon's head and destroyed it forever. King Alistair delivered the eulogy at Aedan’s funeral but the Grey Wardens recovered Aedan’s body, and interred them at Weisshaupt in a magnificent tomb next to Garahel's. Though he did not romance any of his adventuring companions, it has recently come to light that the late Aedan Cousland had a thing for barmaids. Over the last decade, a number of Aedan's prior dalliances have come forward and presented the late Warden's still-living brother, Teyrn Fergus Cousland, with the consequences of Aedan's carelessness—the consequences themselves being a number of children born out of wedlock, many of whom were conceived well before Aedan became posthumously named the Hero of Ferelden. As such, the Teyrn's had his hands full over the last thirteen or so years.

• Since they weren't the Warden, all other "Origins" from this installation are potentially alive (i.e. available for adoption), including: a Fereldan Circle Mage (named Daylen Amell, if male, or Solona Amell, if female - Hawke's cousin, either way); an Elven Mage (named Alim Surana, if male, or Neria Surana, if female); a City Elf (named Darrian Tabris, if male, or Kallian Tabris, if female), a Dalish Elf (named Theron Mahariel, if male, or Lyna Mahariel, if female); a Dwarven Noble (named Duran Aeducan, if male, or Sereda Aeducan, if female); or a Dwarven Commoner (named Faren Brosca, if male, or Natia Brosca, if female).

• Due to his death, his role in the narrative was suceeded by an Orlesian Warden-Commander by the time of the Awakenings DLC.
• Coin given to Bevin for the boy's sword in the years prior afforded Bevin’s sister, Kaitlyn, the funds to move to Denerim and open a foundry that greatly increased her wealth and where at court she, by pure chance, met Teagan again, who was then still the Bann of Rainesfere—within months, following the end of the Fifth Blight, Teagan and Kaitlyn were married.
• Bella renamed Recliffe's tavern "The Warden’s Rest" in his honour.
• Avernus' ethical research led to the mage's discovery of a concoction that extends the lives of Grey Wardens, previously doomed to shortened lifespans after their Joining, to unnatural lengths. His research served as the precedents that inspired the the Grey Wardens to search for a way to prevent the Calling.
• Though he did not romance any of his adventuring companions, it has recently come to light that Aedan Cousland had a thing for barmaids. A number of his one-time flings have come forward over the years, presenting Fergus Cousland with the consequences of his late brother's indiscretions.
