Is that actually lawbreaking? It seems like a grey zone to the tune of animal necromancy to me.
The law says "thou shall not swim against the current of time": that is to say, no time travel. Locally changing how it flows isn't traveling strictly speaking.
Attacking McCoy like this is a clear admission of involvement, but still.
It's the rationale that
@Yog directly have for his plan.
There's nothing to say we shouldn't address this problem in more detail, but the context of this discussion is the immediate complications of being at war with people who will use mind magic to infiltrate and assault your people.
Maybe I'm not fully addressing the entire spectrum of the warlock problem, but the current plans wholly ignore the mind magic violation aspect of it.
We could build a splendor, work through like four concurrent political flusterclucks, and still have nothing at hand to deal with people being magically subverted in the manner that raised these concerns in the first place.
