Lambert was Lord Seeker, not a templar.
most of them, Viv didn't join the war and she is probably not the only one.
Not to mention in some of the circles (most likely in the free marches) the Templars tried to kill the mages even the ones who wanted nothing to do with the war (as hinted at in human mage inquisitor origin story).
similar to not all Seekers and Templars didn't join in on the war.
I said he wasn't a templar in that post aswell i said he kept the mentality from when he was. 
and viv isn't a grand enchanter so most likely she was just at the royal court when the whole lot of them escaped.
I've read Asunder 3 times, where we disagree is that there had to be war. a templars duty is to serve the divine and follow the accord. But both of those were thrown out in order for lambert to have his war.
there are gallons of blood on both sides through the entire conflict. but the war? the war started because of lambert. there was no need for templars to do what they did and this crap about serving and duty is exactly that. If they cared about duty they would never have stepped out of their role as protectors in the first place.
The templars problem is think they should rule mages, its not their job and never was. Which is why the seekers and the divine had oversight. Lambert pissed all over his duty every step of the way, not only did he not reign in the templars he brought in ever more draconian measures including ordering executions of people who were following the divines orders.
you can't pick and chose what the role of a templar is, their role was to protect mage's and mundanes from each other, serve the divine and return apostates to the nearest circle. you can't just drop the first two roles of Templars.
and no you don't use violence against people "rebelling" unless they are violent. Tyrants do that. Which is what lambert was involving into, spitting in the face of the divine and trying to rule of Magi with a iron fist. like it or not people have rights whether you fear them or not. Suggesting they should be blamed because other won't allow them to have freedom is nut's.
oh you're being raped and murdered? turned into zombies? better just accept that else you're responsible for the people doing the raping murdering and zombifying deciding to murder you all on a much much larger scale.
Like it or not Magi "rebelled" for their freedom, the fact they are powerful and you fear them doesn't mean they don't have rights.
1-the post about asunder wasn't towards you, look who i'm quoting.
2-the templars job is to protect the common people from the mage's and the mages from the common people. they decided they knew best and left, the templars were doing their exact duty, the mage's abandon their own.
3-mage's are inherently different from mundanes and therefore cannot be treated with the same guidelines and rights of common people. mage's are inherently not equal to mundanes and cannot be treated as equal otherwise you get another corrupt and rotting tevinter imperium on your hands.
they must being in there gilded cages for the protection of the world and those who prove themself to have control of their magic and unhostle and selfish ideal they should be granted to live outside of circles. they do not deserve freedom just because they exist as a weapon, weapons must be watched, its the same reason they don't give every peasant a sword.
and as much as i love the divine, lambert had all the right to break away from the templars when she kept him from his duties. if anything the divine betrayed the founders of the chantry, and so did all the enchanters who broke the law their forefathers made with Emperor Drakon and Divine justinia I to create the circle's.
also the templar role is set in stone, they are to hunt apostates and protect the common people from the mage's who become selfish. hell even fellow enchanter viv has said the mage's who started this war were selfish. and didn't think of the common folk. beucase that's the truth, they lived for so long in their own worlds they thought themself so important, while the templars knew what they were protecting, knew the destructions mage's can cause, the mage's on the other hand are untouched by the reality of the situaition and dont comprehend the world they live in and the fear and destruction they cause so often, its like a dog wagging his tail, he doesn't know he is knocking over your stuff, but you still must make him stop and be more careful, but since its a part of him, he doesn't know.
