A Gift with a Narrow Use
Sensing Minerals
Paul Carpenter discovers he can identify bauxite deposits through a physical tingling response to photographs.
Skill, Not Omnipotence

Understanding Has a Duration

Understanding Has a Duration

The Portable Door’s Cost

The Portable Door’s Cost
Travel Without Ordinary Expense
Paul can visit distant cities during a short interval, but money, food, and other benefits do not simply return with him.

Magic Cannot Fix Desire
