Day 1 after Arthur's death.
The initial piece of news that swiftly circulated throughout both kingdoms concerned Saisha's alleged collusion with a cultist organization as a means of retaliating against Edinburgh.
Demonmir had already been declared as one of the most wanted cultists and criminals by the Anfang Alliance. So when Arthur's proof of Saisha's collaboration with Demonmir came to light, the masses of Edinburgh supported his actions against Layos' army with all their hearts.
Arthur had taken deliberate steps to ensure that this news reached the masses of both kingdoms. He had also strategically informed multiple authorities within the Anfang Alliance, thereby preventing any attempts to suppress the information.
This revelation, along with the evidence Arthur had brought to light, served as the foundational justification for his audacious attack on the Layos army base.
