After Trin told Valerian to go ahead and the young man came to stand in front of Wakar. The commander of the Lunakes revealed slight fear in his gaze. The young man in front of him was simple from any angle. Killing thirty people and capturing a leader in a blink and even when he was killing them. 

Valerian looked at the commander and without saying anything, he condensed a blob of water above Wakar's head. Then he said, "This blob of water will release a drop every five seconds. The drop of water will fall on the center of your brows. The interval will shorten every ten minutes and gradually you will feel like this drop of water is a hammer. The constant shockwaves will make your brain turn to mush from the inside." 

The seven chiefs and Trin were surprised when they heard this. Valerian walked around the chair and using a wood spell tied Wakar's head in a fixed position where the drop of water would certainly fall on the same point.
