The Dragon Reborn Ch:55

As if to answer him, a blazing shaft like the one Moiraine had made shot out of the shadows among the
columns, straight toward his chest. His wrist twisted the sword instinctively; it was instinct as much as
anything else that made him loose flows from saidin into Callandor, a flood of the Power that made the sword blaze brighter even than that bar streaking at him. His uncertain balance between existence and
destruction wavered. Surely that torrent would consume him.

The shaft of light struck the blade of Callandor - and parted on its edge, forking to stream past on either
side. He felt his coat singe from its near passage, smelled the wool beginning to burn. Behind him, the two
prongs of frozen fire, of liquid light, struck huge redstone columns; where they struck, stone ceased to
exist, and the burning bars bored through to other columns, serving those instantaneously as well.

TheHeart of the Stone rumbled as columns fell and shattered in clouds of dust, sprays of stone fragments.
What fell into the light, however, simply was not, anymore.
A snarl of rage came from the shadows, and the blazing shaft of pure white heat vanished.
