Crypt Flayers

The rarest of the king's blessings produces Crypt Flayers: mordants remade with vast leathern wings, who understand themselves to be angelic knights, the living image of the radiant heroes in the court's tapestries. They serve as heralds between the grand courts, bearing proclamations they believe inked on vellum and sealed with gold.

In war they plunge from the night sky ahead of the host, and their arrival is announced by the sound that gives the courts half their dread reputation: a shriek pitched to burst resolve, and more than resolve, in all who hear it. The Flayers themselves hear a clarion, a silver trumpet sounding the king's advance, and they scream their hymn gladly.
