We all know that Deathwing will emerge from Deepholme, the land ruled by Therazane. It is also public knowledge that Therazane is more benevolent than her Old God masters, and thus, is very likely pained by the destruction of the land they desire. We also know that Deathwing is a tool of the Old Gods and the Earth Warder. As is, it seems likely that in Deepholme we will be assisting Therazane versus servants of Deathwing, the new Earth Elemental Lieutenant (Lord/Ruler).
Thoughts?
P.S. From wowwiki:Therazane the Stonemother is ruler over the earth, dirt, rock, and mountains. She is revered by all earth elementals and creatures that dwell underneath the ground. Some druids of the wild see her as the embodiment of all that is peaceful and calm about the world. Some sages believe she feels pain whenever the ground is sundered and weeps at the destruction wrought by Deathwing and his ilk. If so, however, she has done nothing specific to oppose the great dragon. Therazane is the most peaceful of the Elemental Lords. She is a patient, loving, motherly type who encourages growing things and loves simply to spend long periods of time relaxing with those creatures that make their homes upon her. She often feels as though she is always at war with the other Elemental Lords: Al'Akir erodes her surface with winds, Neptulon beats his waves constantly upon her shores, and Ragnaros is a blazing furnace that churns at her fiery core. She would be perfectly happy if the three of them would just go away. Therazane is slow to anger and attempts to avoid combat whenever possible.
