Wars between planes broke out, centred around the material plane. The fiends of The Nine Hells rose an army to attack the Material Plane through Setton Regis, in order to control the Nexus Porta. Alliances formed between positive and negative planes on either side, though many stayed neutral. War threatened to unravel the fabric of reality. A calamitous power release occurred that devastated the city of Setton Regis killing many of the inhabitants. The original line of kings was lost. The last of the old Kings, King Tempin sacrificed himself, destroyed the Nexus Porta, having ordered the dismantled pieces to be scattered across his empire so they could not be found.
