A Descryer is an elf that has the special ability to can sense the potential in another. It is known to be a rather rare ability, with Councillor Terik being the only registered one. Elves can naturally manifest the Descrying ability. Councillor Terik, however, usually refuses to descry someone, and when he does, will not share the results because he doesn't want to "unduly influence" anyone. The only elves who have been Descryed (that we know about) are Alvar, Fitz, Sophie, and Keefe.
