He hurled the Abyssal Gate directly at Prague Castle, immediately causing severe friction between the Law governing the land.
Like the gravitational forces of two colliding planets, the stronger would tear apart the weaker, but as it was the Law of a kingdom, even Shaw needed a considerable amount of time to destroy it.
Impatient, Shaw set about causing destruction, drawing power from behind the Abyssal Gate and even sacrificing his own source of power to swiftly suppress the kingdom's Law. He then used the Godblood Warrior Legion to attack the Royal Capital, plunging the kingdom into chaos first.
Meanwhile, Shaw moved on to his next target, using his Legion and the Abyssal Gate to continue the suppression, as the Abyssal Gate was vast enough to suppress one Law or many.
