[Ygorl]

A good point.
If this proposition passes, Ygorl is happy to not prosecute roguehood as long as Apep withdraws his armies and makes modest reparations. In that case, it would not set a precedent.

Though, I don't think it would be a terrible precedent to set; the proposition is not creating new law, rather it is a poll of all Wyrms as to what the existing law already is. There's certainly cause for lenience when a law is violated through misunderstanding or ignorance, but such ignorance does not mean that the law was not violated.
...Especially in the case of such a diabolical attack!
