The Access Key to the choedan Kal
From Robert Jordans The Wheel Of Time
“A carved white stone figurine perhaps a foot long, lying on its back, a man holding a crystal sphere in one upraised hand.”
-The Shadow Rising, Chapter 68 - The Traps of Rhuidean
“...a great, half-buried statue... of the huge crystal sphere in its hand, glowing like the sun, pulsing with the One Power.”
-The Shadow Rising, Chapter 68: The Traps of Rhuidean
“...he produced two statuettes a foot high, a wise-looking, bearded man and an equally wise and serene woman, each in flowing robes and holding aloft a clear crystal sphere. From the way he handled them, they were heavier than they appeared.”
- Winters Heart, Chapter 11: Ideas of Importance
“A prick of light grew in front of Rand, sprouting from the center of the access key.”
-The Gathering Storm, Chapter 47: Reading The Commentary
“The access key began to glow in his hands.”
-The Gathering Storm, Chapter 50: Veins of Gold
