Double Seas

At the entrance to the Sub-Realm, one could see the hovering mountainous demon beast, the sole individual in the region at present. All it did was keep its eyes closed while seemingly in deep thought. Though, once one looked at it closely, one would actually notice that it was...sleeping.

The overseer of the Sub-Realm wasn't monitoring the conditions within but was instead taking a peaceful nap. 

Suddenly, it was startled for a moment, shooting up in alarm upon seeing the clouds above condense rapidly and darken instantly. Bolts of lightning flickered around as the cloud was building up power. 

Then, followed by a flash, a bolt of lightning struck down, coming to a stop before the mountainous demon beast's face. It lacked the power and grandeur of a normal lightning bolt. Nevertheless, the mountainous demon beast took on its most respectful posture, acting subserviently.
