Before the war? Yes, months before it. Five or six months and two rulers ago, actually. Back when Me'hoe was being a twat and trying to organise a coalition of southern realms to invade the north. Back when Ohnar was doing everything it could to deliberately antagonise Arcaea and Sorraine. And even then, Velax never would have invaded without an ironclad casus belli. But then you got yourself murdered and Ohnar got itself a semi-competent ruler.
Invading Ohnar West had never been discussed with Mathilda. And as Indirik has pointed out, Sorraine apparently didn't want Arcaea involved, in any case.
