There are no Electric

Tevinter is the only place in Thedas not to make use of Qunari technology. Everywhere else? Look, the Qun might have had a reputation for war in the past, but now all they do is make very useful machines who may or may not be watching your every move and reporting back to a centralised database we're just kidding ha ha.

The Iron Bull, a Hissrad-class unit, might have some prior malfunctions on his record but he was recalibrated post-Seheron and now he's just fine, and not obsolete yet, thank you very much. A little observational work is far below his original specifications, but that's a good way of making sure there are no unfortunate reoccurrences.

Then Madame de Fer decides that Dorian Pavus needs someone-- or something-- to make sure he doesn't actually work himself into an early grave-- and, well, Control Central jump at the chance to have him keeping a close eye on a Tevinter mage.

This is how Dorian Pavus ends up with a very large, very battered Qunari android standing in his living room.
