Simon is working on a treatment for River to make her a bit more stable, and right now is starting out small with herbal sedatives and the like. In the near future he'll start trying to make something more drastic, something to temporarily weaken her link to the Fade in order to quiet the voices she hears (hopefully opening one or both of them up to be able to participate in missions outside Skyhold). I'm imagining it would essentially be a weak and temporary sort of Tranquility in a bottle, and I wanted to get your input on whether or not that would even work or how long it would take, what sort of materials he'd need, etc etc.
