Significance of Dragon's Orb

This is a magical orb that the mage Raistlin keeps with him at all times. The orb contains good and evil and is bound together by neutrality. When the orb is being used it radiates with light and it grows to the size of a child's ball. When the orb is not in use, it shrinks to the size of a marble. This is the magical item that Raistlin uses to escape the maelstrom.
