I think that codex might've been retconnetted. I recall that in ten new timeline on the site the Nevarran Accord happened really close to the Chantry's formation. Or I'm remembering wrong.
The mages are now free of the Circle. Yes, the templars are hunting them, so they're the aggressor, but that doesn't change the fact that mages are acting in a terrible way. My 'equals' was referred to how they're acting in the world.
I think the "History of the Circle" codex addresses the inception of the Circle Towers, as opposed to the (Andrastian) Circle of Magi.
Helping the templars doesn't seem like a viable option for my character (although I'm sure that's not the case for pro-templar players, and I hope they can side with their favored faction). I'm genuinely curious what kind of conversations might ensue between my elven Inquisitor and Vivienne before her participation in the campaign; she must have questions about the direction of this organization.
Has it been addressed if the Hinterlands will address the Dalish Boon (with it being a sovereign elven state if the Dalish Warden performed the US or asked for the People to be given their own land), or has that gone the way of the Magi Boon, and players should just pretend that it never happened because the royal boon effectively means nothing?
