According to The Chantry: “Once a mage passes his/her Harrowing they cannot be made Tranquil.”
However The Templars overlooked this “law” and made mages Tranquil as a means of punishment. Meredith is a good example of this. It did not help matters that The Chantry who was aware of the Templars using Tranquility in this way did not step in.
Why?
Those who are made Tranquil are generally left to enchant items. Which in turns gives The Chantry a large chunk of income. The more Tranquil, the more income The Chantry receives. The Chantry cannot make every mage Tranquil this would cause an uproar.
Let us say that three mages at a Circle were made Tranquil because he/she did not pass their Harrowing. Well now The Chantry has “X” amount of income coming in. But if three mages were made Tranquil for whatever the crimes they committed The Chantry now has six mages instead of three bringing in more income. Thus The Chantry is willing to look the other way.
While The Chantry is willing to look the other way, there are those who are against such an abuse with the Rite from both mage and non-mage alike. Which is part of the reason why there are mages who are against The Chantry.
Remember: The Rite not only takes away a mage’s magic but also removes all their emotion, thus leaving them a hollowed shell.
From my view point giving Erimond Tranquility MAY seem like the proper punishment but in fact it is not. Wielding the brand as a means of punishment makes you just as bad as The Templars and The Chantry for not only abusing the Rite but also going against Chantry law.
Most mages would rather die than be made Tranquil. IF I were a mage, I’d feel the same way.
In my choice, I gave Erimond death. Yes, that is what he wanted, but at least I feel better knowing I did not stoop to the level of breaking The Chantry’s law.
Remember too there MAY be a way to reverse The Rite of Tranquility. What if it can be done? What happens if Erimond was made Tranquil and is “cured?”
For me making Erimond tranquil is not a solution just the start of a whole new list of problems not only among the Mages but also MAY bring up worse problems in the future.
