A local covenant has made itself a general annoyance to the Provencal Tribunal, and recently one of the members made a showy effort to bully a maga through certamen. This same covenant is widely suspected of covertly acting to undermine and possibly destroy other covenants sheltering Cathars - their mission is to destroy the Cathar heresy.
Menacing Joia de Lua of Jardin was a mistake, though; a coalition of 15 magae, led by Dama of Merinita, declared a wizard's war on the four members of the covenant, saying that their presence was intolerable and that if they were still in the Tribunal at the next full moon, the start of the war, they would be destroyed. They should not return.
We have a quaesitor in our covenant, and she was summoned to the emergency Quaesitorial Council to hear the appeal for invalidating the declaration. This matter was discussed around the table and the conclusion was that:
The appeal to fairness was no bar: being outnumbered 15:4 does not invalidate the war.
The Code does say that Wizard's War is between two magi. The appeal that the 15 magae had declared war in a single message was no bar: this is merely a condensation of form. For all practical purposes this was 15 individual declarations against each of the 4 magi. There is precedent in the Peripheral Code of Provencal for inter-covenant war.
The appeal that such a declaration was an effort to deprive the magi of their magical power, in the form of books, devices, and vis stocks and sources was generally not a bar. Most of these were chattel goods: portable. The magi could take them along if they (wisely) departed rather than stand and fight. Unmovable property damage and denial was simply a cost of the war. However...
The PC Quaesitor pointed out that the effort to provide mercy, Get Out or Die, and the implication that they would not chase them beyond the Tribunal, would forcibly separate the magi from their vis sources if they departed. This was a weak point but potentially a cause for Tribunal review. This was reluctantly agreed to by the other players in NPC quaesitor roles.
So, on the next full moon, a more simply worded declaration asserted that the magi were intolerable, and that the undersigned magae would destroy them, beginning on the follow full moon, and reworded to clarify that the magae were each declaring war on each of the magi. This did give the covenant an extra lunar month of preparation...
I thought people might be interested in this spontaneous in-play opinion. My plot: it surprised me a little.
