Founding
At the height of The Rotspur Ravage, with seven of its clients campaigning for a normalization of relations with the rest of the world, Delos'Nordan opted for expulsion of the dissenting representatives. This has come to be known as the Last Crisis of Thrys.
This would lead to The Raventide Revolt and the eventual secession of Revansgar. The Council of Thrys has had many crises throughout its history. In Revansgar (and thus the rest of the world), this event is typically referred to as the "Last Crisis," for it prompted its eventual secession. In Delos'Nordan, it is often called "The Border Treason."
