For the Ethereal purposes, this is not a pocket-dimension. The rules of the Ethereal apply here.

Though not entirely a place itself, this field among the sands of the Ethereal desert known as the Grounds, this place is absent of passage of time. People entering these fields rarely return back into their own time, losing themselves to a vortex. Beings that are not capable of moving in time lose their ability to move on their own altogether while entering the Frozen Time.

Rumors mumble that some powerful Beings are capable to use this field to detach themselves of time and bend it to their wills. Such power is rumored to be used by The Deathwatch.
