A Descryer is an elf with 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 by the knowledge of Sophie Foster are herself, Alvar, Fitz, and Keefe, though Terik said he used to Descry lots of children for their parents, which implies there are many others that have been Descryed.
