Quotes
"Deepholm was a slow, quiet place. Always alive.  Steadily moving.  Never rushed.  In this time, I strived to become one with the earth, and to a large degree, I succeeded."

"Later, the Earthwarder returned, injured. He did not upset the balance at first.  He'd stayed here before, and we knew him.  The shift did not truly begin until the Twilight cult joined him."
