In the past, among the ranks of New Sharandar had been an eladrin warlock known as Zoramadria.
Zoramadria disappeared over a decade ago, thought to be dead, but Commander Wintherwhite of New Sharandar suspects that she may actually be alive and that she may have switched sides to join the dark fey. Zoramadria was a powerful spellcaster and one who specialized in magic of the planes in particular: it was possible she might be responsible for the strange planar phenomena around the Academy of Magic or the strange effects on the Tower that had been seen.
In 1494, she is apparently teaching advanced illusion magic at the Academy of Magic.
