given that mages who don't want accept current rules end killed or turned into zombie what stops us from doing that.Especially that peoples will want burn mages themselves after that crap they caused now hehe...
Templars what Thedas does never have very much(just a few thousand with ~13 KC in whole Thedas 13 Circles before asunder), suck agains mages and they are very very expensive and need training for years to have their abilitys what is mostly useless against deamons and normal mages
and now Orlais Templars do not have anything and separate from Orlais Chantry what makes them enemys even for Orlais peoples
they can only kill childrens without good magic education, and even childrens beat templars)))
witches, apostages, dalish, barbarian mages, dragon worchipers, trained circle mages and magisters are beat Templars without any problems, and many non-mages in Thedas will never support Templars and fight against them
even now no-one will support survived Orlais Templars exept some Orlais, Starheven and minority of Ferelden peoples...and even Orlais Chantry and Orlais rulers with many nobles(many are secretly mages) support mages and they always would need them and even Templar Order was always need them(no phylacterys, no Lithanies of Andralla, no enchanted weapon and armor and no money) and they cant and would always weak to start a war against all mages, even bad ones as from Orlais Chantry Cirles
Rivain, Nevarra, Tevinter, Anderfels(Grey Wardens who is rule the country), mostly half of Free Marshes kingdoms will be on mages side
all barbarians, non-andrastans, dalish-elfs and dwarfs would be on mages side too
majority of Thedas hate Orlais, hate their Orlais Chantry and especially their Orlais Templars..and after Orlais Templars now separated, have mostly nothing and do not have most of Orlais nobles and even their Orlais Chantry support, so Orlais Tempalrs now are mostly noone...some fanatic terrorists and many see red templars
