Perhaps my favourite worldstate that I've ever done (that can only be partially represented by the Keep), is my 'traumatic playthrough'.
I start off with a Dwarven Noble Rogue, who, like all others, had her older brother be murdered, had been betrayed by her younger brother, got exiled, and had her father die as a result. Well, this was bad, though she truly did not understand how bad until after Ostagar. See, with Lothering behind her, she rushed home. To Orzammar, and saw the mess that had happened thanks to Bhelen. Nevertheless, she stood by his side. Defeated Caridin (Shale died too), and then came home with the crown. Realizing who Bhelen truly was, she gave the crown to Harrowmont. And slowly went mad. Following Dagna's request, she went off to the circle. Her actions lead to the destruction of the Circle of Fereldan, and the Templars won. Telling Dagna the circle was destroyed, she went to the Dalish. Hating magic, at this point, and seeing a corrupt leader in the clan's Keeper, she chose the werewolves. Her actions continued to haunt her. Wanting nothing more to do with humans, or magic, or the rest of the world, led to the death of Isolde, and despite romancing Leliana, killed both her and Wynne after poisoning the Urn of Sacred Ashes. She ended all this, by letting Anora take the crown, not preparing or helping Redcliffe to fight, and committing suicide via Archdemon.
The Warden-Commander, Orlesian of course, was an elven blood-mage by the name of Blossom. She was very chipper. She made typical Warden decisions, inviting everyone to become a Grey Warden, defending Vigil's Keep, and allowing the Architect to stay alive. She also chose to protect the fields, rather than Amaranthine.
Follow that with Malcolm Hawke (Jr.), a warrior who started off normal. Was rather diplomatic in Act 1 and 2. Romanced Isabela. Mostly stuck to sending mages to the circle, thanks to Bethany, who said she was happy there. Let Petrice do what she had to to get the Qunari out. And his mother died. Aggressive since, sided with the Templars and killed everyone in his way, crying all the while. Kept Charade away from Gamlen, to protect her from his doomed family, and even let Meredith kill Bethany. Became viscount, but I doubt he's a good one.
