I was made Tranquil, once, as part of the initiation rites of becoming a Seeker. I did not know it, or understand it once it had been reversed. Nor did I understand that Tranquility could be reversed until the truth was revealed to me by Lord Seeker Lucius.
It is a disgusting practice, and one I have been researching how to reverse.
It is likely not much, but it is a beginning. All things must come from meager starts.
