"A Vanisher is an elf with the special ability to let light pass through their bodies. This allows them to turn invisible. They blink in and out of sight as they walk.Vanishers also seem to be able to flash-step; intermediate and advanced vanishers can do so. This was shown when Della appeared in the water without getting wet, and Biana vanished to the other side of the room. When enhanced, they can turn turn others invisible."
Lady Adriana Conwyn-Jennings, or Lady Jennings as she prefers to be called by, is perhaps quite unique in the sense she is currently one of the few, if not only, transgender mentors. She teaches Vanishing for TBD levels, alongside Physical Education for the older levels (5-8). A caring and soft-spoken mentor, she never expects much beyond an honest effort... and respect for all the prodigies. She will not stand for any discrimination, and such remarks will be among the very few things she'll take very seriously.
