Celene or Gaspard? Whichever one I can use as a puppet ruler for Briala so she can improve the lot of Orlais' elves.
Apparently you have to complete 12 Impossible Tasks in a specific order to get Celene and Briala to reconcile, which my characters wouldn't know how to do without meta information from me, and which I can't really support anyway since I've wiki'd a little of what their relationship was like in The Masked Empire, and I think it's too toxic to put back together. Plus, apparently Celene butchered 3,000 elves in an alienage when her own power got threatened and knowingly ordered/allowed the murder of all the elves in her palace (including Briala's parents) while sleeping with Briala, whom she often gave grief for being elven and dark-skinned anyway. Wow, I cannot support her.
Gaspard isn't much better. He's more up-front about being a power-hungry jerk, but he's still a power-hungry jerk. And a militaristic one who seems keen on regaining Orlais' lost military conquests, and is openly racist and disdainful of Briala for being an elf. I'm all too happy to give him the throne he wants... too bad he didn't specify that he wanted to be the one in charge. Oh well, sucks to be him. The elves of Orlais have a future again, and that's what I care about.
