Huk, Orlais is mentioned in passing in DA:O and it's been years since I played DA:2 but even then you were stuck in Kirkwall. afaik, DA:I is the only instance where Orlais is prominen outside of Lorebooks
I mean... a major party member is from there in Origins... and her accent doesn't hide the fact. ((not to mention nearly anybody who is aligned with the Chantry lol. A lot of them are Orlesian.))
