Nobody at the Palace could relax just yet. With the threat of the curse spreading through the area, and the damage that it could do before it was purified, everyone was on edge, even the more powerful Demons, who were unlikely to be seriously injured by the effects.
But what was more concerning was that they were unlikely to be the only targets of this effect. If the Fallen Crusades had gone so far as to sacrifice their own Archbishops in order to try to score a Demon King kill, they would definitely be targeting more than one location.
The King had already sent an official message to his allies, but none of them were under attack at the moment, which led him to believe that it was the more chaotic and unaligned smaller Demon Nations that were under the most severe attack.
