The first thing Aria notices, when she wakes up, is that her throat hurts a lot and her gut hurts not at all. This is pretty weird, given that she distinctly remembers being stabbed through the gut with a spear, and that's the sort of thing that really should keep hurting for a while. It takes her a second to remember what's up with the other thing - she drank something in the cave, before she collapsed and after the spirits told her your life is of no value to us. Doesn't actually know what it was, but it burned worse than the darkspawn blood and it took her down twice as quickly.
But she did make the deal. She'd offered them her life for Draconis's, and they'd laughed at her - not because they couldn't raise him, but because they only traded things of value, and her life was of no value even to her. So she'd offered to trade away her death, on the grounds that she and lots of other people seemed to want it. She'd known it wasn't going to work, but it had. They'd said it had, anyway, though there were terms and conditions and something about a bargain involving twelve labors, although her brain is too foggy to remember it all right this second.
She opens her eyes. Alistair's carrying her back through the forest. She turns her head and sees that Draconis is walking beside them, looking pretty convincingly not-currently-dead.
"D'we win?" she asks, though talking actually kind of hurts.
"Apparently," says Draconis. "I was sort of out of it."
You were dead, she doesn't say, because that would require talking.
She gets Alistair to set her down, and she checks herself for other wounds, and nobody asks her what in the void happened, and they all walk silently back towards the fortress for a while.
