Except that our Legitimacy Stat is straining on 4/3, above the normal norm. And we have 20 Prestige. Prestige is rather easy to get and is uncapped.
If they come for us, then sure. Defensive Wars is our speciality, let them come..... but don't assume that it is certain that they will.
Let transgressions past past. Under a much more favourable circumstances, we'd have a Diplo Hero to sort things out. But as it stands, let old wounds heal with time. Do not rise to the sabre-rattling. Once the Hero and the generation after his dies, we can began more serious overtures. Slowly trade with them, then make it so that they become allied polities with us. Remember, we play the long game.
[X] Recognise the new Cadlon of the Maradysh as their new leader, (-1 Legitimacy, -2 Prestige, Maradysh are no longer a vassal of the Arthwyd,)
It stings me, as an advocate of the Midlander Vassalage that this has to happen, but c'est la vie. Acknowledge that the Maradysh are their own people. That they have the right to forge their path. And again, in time, we can start a new chapter in our relationships, where old bloodfeuds are but distant and faded etches on the buried stone tablets.
