Sedatives are fine, but at this point we can't approve the concept of Tranquility in a bottle. Something like that would likely have revolutionary effects on politics in Thedas as a whole, and we don't want to provide any easy outs to the questions of whether Tranquility is necessary, whether Templars are necessary, etc., since allowing people to struggle with those issues is a lot of the fun of this universe!

We might be able to work with you on something more akin to a Saarebas collar/system--it wouldn't have to look like one, necessarily, but something using similar magic/technology and that needs to be worn, and which would be severe enough that other mages would not be all right with having it presented as a viable way to control them. If that's something you're interested in, we'd suggest having Simon turn his research in that direction and talk to the local Qunari who might know more about how the collars work or help him figure out how to find one to study. If you're interested in running a player plot to let him acquire a collar, we'd be happy to facilitate.
