It isn't a ****** lobotomy.
It's a disgusting and inaccurate comparison.
So, the only disgusting part here is the inaccurate comparison... not the ritual itself?
Tranquility doesn't impact the physical body.
Actually, I'd argue that it does?
Whatever happens with Tranquility probably has something to do with suppressing the amygdala, which regulates emotions? Even if Tranquility is reversed, Pharamond was shown to suffer from extreme emotional irregularity afterwards, either because the amygdala has suffered from some degree of atrophy over the years being Tranquil, or was damaged in some way during the Rite itself?
No one dies from a botched tranquility.
Just curious, do we actually know for certain that no-one's ever died from them?
In Asunder, Rhys mentions that the Circle Mages are used to people they know disappearing unexpectedly and never seeing them again, but the Templars refuse to discuss the matter with them, so they never knew if they'd been executed, made Tranquil or sent to another Circle?
For all we know, some of those mages that were listed as "executed" were really killed when the Rite of Tranquility went horribly wrong? It'd be far easily for the Templars to simply list them in that way to make it look like they're not screwing up, plus no procedure (or magical ritual) is likely ever guaranteed to work all the time without complications?
