Time seemed to have slowed as the imminent sneak attack of Lucian's approached Kyran. He could not cast any defensive spell because of the latter's overwhelming pressure, and due to the rules of his Dimension, casting escape skills like teleport or warp was also impossible.

Kyran could not use that technique simply because Lucian saw him use it when he tried to escape the latter's pursuit back in the Lower Realm. Furthermore, even using the Dragon Step would not guarantee Kyran's survival. This was how close Lucian's attack was to his neck.

However, True Void was too far away. True Void also could not teleport to Kyran's location because of Lucian's Dimension.
