This story takes place around the time of Act 3 in Dragon Age 2. If you just kept the Warden alive it's mentioned he should be back in Denerim

"You told me their wouldn't be a crowd", Daylen muttered to the King as they rode side by side through the streets of Denerum. "And you told me you would only be gone on a brief mission", Alistair smiled sardonically. The streets were packed with cheering crowds. The King wore his brother's armor, a massive, frankly ridiculous looking suit of gold painted plate. Ridiculous though it may have been, it had meaning to the people of Ferelden. A reminder of what they had triumphed over. Daylen wore the robes of a Warden, enhanced with a bit of armor to denote his role as an arcane warrior, and, as the Revered Mother had put it all those years ago, keep from looking "to mageie". He looked every inch the magnificent hero.

Rich and poor, old and young, men and elves, all lined the way to see the famous Hero of Ferelden. Most only knew him by that name, Alistair had written to him shortly after the Blight that dozens of newly born children had been named Warden, in apparent reference to Daylen. The whole thing made him vaguely queasy. What was I supposed to do let darkspawn destroy everything? It wasn't like he even had a choice, it was join or be sent to the Aeonar, and the Darkspawn would have followed him even if he had deserted.

Ferelden had many heroes. One of the greatest was riding alongside him, doing his best to pretend to share the crowd's joy at Daylen's return. Alistair, Elissa, Rina, the Blight, all of that seemed like a lifetime ago. He had left the Wardens in all but name when he chose to go though the Eluvian with Morrigan. He'd figure Alistair wouldn't really miss him, and that the rest would understand.

"Events got ahead of me", he said meekly. "Six years seems like a rather long time for a mission", he replied, in his customary snark. "I hope Queen is doing fine", he awkwardly tried to change the topic. Alistair shot him a look that felt something close to pity. "Elissa's a lot better than when you last visited. Truth be told she's far more eager to see you again than I am.", their was a weariness to him. Everyone knew King Alistair would have preferred to have stayed in the Wardens, but Daylen suspected this weariness was about painful memories, crawling up from the ground like Genlocks. Daylen had a lot of those.

The King looked ahead. He looked very different than the young Warden scarcely older than Daylen. Makers breath he almost looked regal. "Lets save some conversation for when we get to the palace okay?", said Alistair. Daylen shrugged. "Fine by me." "Oh and one more thing, were still not even.", it almost seemed like a wave of tension had departed Alistair. "I never thought we were", Daylen replied sullenly.

Shoutout to the intro to Halo 2. In case you haven't already figured it out, this story will not be told in chronological order.
