Julius nods, taking a pause as if to sort through his thoughts before beginning. Ultimately, the first half of Strange's request is the more straightforward, so he starts there.

"As I've sure you've gathered by this point, Thedosian mages can work magic because of the way we connect to the Fade. At its most basic, the rite of Tranquility severs a mage's connection. It means they can't do magic anymore, and it also means they lose the ability to dream and their ability to access most or all of their emotions. It was once thought it made them immune to demon possession, but research has since suggested they are merely unattractive targets."

He exhales, slowly. "There was once a time, in theory, where Tranquility was for one purpose only; mages who chose not to undergo a Harrowing process. It was supposed to be a last resort to prevent mages from hurting themselves or others. In our Circle, in my time there, it generally wasn't used lightly. That wasn't true of all Circles. It was abused for political purposes, personal vendettas... In theory, a Circle's First Enchanter had to agree before the rite was performed, and theoretically it was against Chantry law to force any mage who passed their harrowing to become Tranquil. But there was hardly a mechanism for mages to appeal corrupt or unfair decisions."

He feels a bit like he's lecturing, but he needs to get through the basics first. He does pause, however, if Strange has any questions.
