Why not tell us that Fiona is Alistair's mother? It took years for the devs to confirm it, and people are still arguing to the contrary.
Anyway, I said it's a logical inference. That doesn't mean it definitely happened, but IMO it's likely for the very reason that Dorian states- he doubts that Alexius (or Corypheus) would leave such an important mission to chance. They're not just depriving the Inquisition of mages, they're hoping to lure the Inquisitor. It's a mission that Alexius can't fail or his son will die. And for Tevinters, using blood magic to get their way is like anyone else popping a lyrium potion- it's just what they do, if they have the capability and need it to get ahead. I'm sure it's left ambiguous for this very reason, i.e. to fuel speculation over Fiona's motives. Except some people won't even speculate, they're too blinded by dat sweet, sweet h8.
are you serious ? Their is no hate and their is Pro Dragon age fan here that know the lore from A to Z and story of each Npc out there . we know that fiona is alister mother . He don't know that and no one should no . He is the king of ferladan . This dicovery will proove that he is half blood elf and a have magic blood . This will litteraly destroy the ferladan Kingdom .
and we here try to act like real leader and from a inquisor perspective not a emotional teen that will go to a trap by a magister that control time magic to save a fool leader tricked by a magic trick and a banch of mage over an army of men trained to fight magic and demons . I m npt a mage heters a try my best to help them and give them rights .
but for the first time in Da serie templar have a job to do . What they trained all their life for . Why they endure all the pain of the lyrium ( see samson story and cullan story to enderstand what rhe chantry do to the templars ) . Not being a police for mages that not was the templar where made for they where made to fight demons and evil magic .
Like demons that pop from the breach and evil magic like alexuis Magic . Vanatory magics . CORYPH magic . They have a role to play now a real one . And i think mages their seilf would really like to join yhe inquisition to fight and not to flee to a magister . So fiona take the responsibility of that and not all the mages . mages will always born in the word . But iffif the order is lost it is lost for ever . Save the order now . AnD make it better for the young mages that will see life latter
