About Refugee Mages or Lefted Templars
Always mages and alliance because you will have full support and loyalty and it would be best in epilogue...Fiona unfortunately cant be removed but she is far better and experienced then loyalist Vivienne-pathetic prostitute for old noble who not even live in Cirlce and become a enchanter for no reason except her loyalism", and she have more influence so it is better to make alliance not force them.
Сhoose a Seekers/Templars-what was lefted of Order after 90% of Rebel Seekers/Templars with their HQ was made themself as red templars and bow to Corynfeus and do all sh*t is not a very wise and smart thing and it is not good for Inquisition because you will for no reason need to restore and support what was lefted from Templars and give them lyrium rather then give it for mages and use it for main reason to study and stop demons and breach...
In Thedas Everyone was choose mages, especially nobles and rulers of the kingdoms, they know that they will have a the most powerfull weapons, crafters and healers in Thedas. even Chantry choose mages because they know that without them they will not have anything, especially money.
Rebeled mages who was a refugies in Redclif are innocent and if you will not choose them to prefer lefted pieces of Templars, Venatory cultists will recruit them and force-put deamons in them like in grey wardens(and they was able to do this with Seekers who support Corynfeus and they let him go in conclave) to fight with their enemies-templars-you who for no reason and sense choose templars
Even Cassandra will choose to have mages and Order was corrupt and dead and already do many very bad things what they cant change
And if you choose mages you can have magister who have researches about "time travel magic" and have some help from Tevinters, their magisterium will have news about cultists and help you.
There is no point and + to save those almost useless pieces what was left from Templars and Seekers, especially by the epilogue when they almost always was become disbanded
Templars was useless and not have any point of existence except that true templars-Seekers want a mindless and addicted mobs(Seekers specially do not make them as true-tempalrs as they do not do a right tranquill ritual) for mages concentration camps and Orlais have "free workers" slaves in alianages
All wars, crusades and all propoganda and all this sh*t what was happened in Thedas was a Seekers job because they for 900 years played as gods and want to control Thedas, the whole orders as Orlais Chantry as it exist never have any point of their existence except that Seekers power hunger and beliefs that they are chosen ones
The Corynfeus was their job they let him do all and they do this and support him without any deamons and mindcontroll
