Rewitt

Rewitt is a solitary and malign Fey who departed from Fey culture a very long time ago in the Age of Wandering and never reached the Fey Court, chosing instead to dwell within the Gravehollow in a citadel known as the Dripping Tower.
Rewitt is of unknown sex and unknown parentage. It is even possible, indeed quite likely, that Rewitt is a member of the Unelmien Lapset, which if true, would perhaps make them the only surviving member of that extremely ancient group (the status of other possible survivors being very doubtful). However, as with almost all "facts" about Rewitt there is a great deal of uncertainty.
Rewitt appears to have a profound hatred for the Fey Court and has apparently aided the Court's enemies on a number of famous occasions, most notably as an ally of the Frost Giants and Ice Sprites in the Second Frost War.

The Fey fear Rewitt more than mortals, who are less likely to have even heard the name. But both Fey and Humans are extremely unfortunate to be caught and brought to the Dripping Tower, where they will be more than likely subjected to the grotesque experiments for which Rewitt is notorious. Very few indeed have emerged alive from that experience.
