A few minutes ago.
As the Hell's spirit witnessed the catastrophic destruction spreading throughout the throne room and then to the entire castle, it knew that it had to act quickly to save the innocent demon slaves trapped within its walls. With a heavy heart, it made a swift decision and enveloped the lower and mid-rank demon slaves in its shadow, teleporting them out of the castle and into the safety of the city.
The teleportation process took several rounds, as there were hundreds of thousands of demon slaves to rescue. Hell's spirit worked tirelessly, knowing that every second counted in the face of such overwhelming destruction. With each teleportation, it felt a mixture of relief and determination, knowing that it was doing its best to save as many lives as possible.
