It takes more than a good shaman to wield the earths power on the level of the Earthwarder. Again from same book:
He felt rooted, solid, deeply wise. Thrall well knew that it was not his own knowledge that he was experiencing but the knowledge of the earth. This was where the ancients dug their roots; this was where bones, over time, turned into stone. He felt bigger than he had ever been, expansive, for all this world was his to mind. managing of time, of life, of dreams and magic. I offer you the earth. The soil, the ground, the deep places. But know that the earth is the basis of all things. It is where we are rooted. Where you must come from, if you are to go to. Here is whence true strength comes. From deep places … within the world, and within oneself. The blessing had not been intended for his ears originally. But it was now. The energies of five Aspects stood together, as they had not done for millennia. And then it happened. The images that the Aspects and Thrall had become in this spiritual realm exploded. Not violently, or angrily, but as if the joy could no longer be contained in anything resembling structure or form. Like fireworks, the essence of who and what each Aspect truly was soared forth. They met, hues of each one, bronze and green and blue and red and black, and twined about each other, weaving the colors together. Like strands of thread on a loom. … To unravel part of the piece, all you need to do is pull on a single loose thread. No, Thrall suddenly thought as the words of Medivh, spoken to him in the timeways, rushed back to him. Not weaving. Threads could be pulled, or broken. They must not interweave; they must blend. … Thrall visualized his color, a pure, peaceful black hue, merging with the other dancing plumes of the Aspects. They understood at once, and each yielded its boundaries. The colors began to blend, turning a single uniform hue of—“He comes!”
Thrall was chosen for this. It takes more than a good shaman. Plus, after the events of which Deathwing splits his soul and grants him the burden of the Earth , Thrall becomes even more powerful. So cry all you want. You’re only embarassing yourself while I give u referencesfor my arguments.
