The immense power of Vakin the Mighty sank into the earth and cracked it up. The n the power spread outwards from the foot he stomped onto the ground towards the incoming army.
As the power spread through the earth, it cracked it and lifted the earth up before slamming it down. This made the immense power travel through the ground like a wave.
Vakin was clearly a giant. But the way he raised the earth to a height of 2 meters and left it cracked in its wake made him look bigger than he was. Everyone who saw him felt it was right that he was called Vakin the mighty.
But apart from admiration towards him, many people also felt felt. Most of this fear came from his enemies, as it usually does.
In this care, if the shockwave that he created with a stomp of his foot were to meet the army, it was likely to bury them with how high it was. So this was a justified reason to be afraid.
