Toz ignored the atmosphere among the troops and combatants on the void metal sheet and concentrated on expanding it so that the troops still on the ground would have a place to stand when they arrived through the portal. The Death Knight, while weak, was still intimidating enough to make sure no one rashly approached him.
However, Toz got a bad feeling. The Blood Fiend should be getting quite close to the troops on the ground. It had taken it pretty slow in the beginning since it was confident that it would catch up, especially when the Alliance of Kingdoms' army stopped moving. But it should have realized that they were escaping and picked up its pace.
