refers to creatures reshaped by the Cabal of Obsidians in their facilities beneath Desolis (The Epitaph).

The remains of this facility, currently has evidence to three creatures reshaped with the Cabal of Obsidians magic: Elves, Satyrs and Trolls.

Trivia

 * In it is known that Faun creatures were created by transformational magics by the Cabal of Obsidians and used with their armies and operations. In the novel, Syenna claims Faun creatures were made from transformational magics on humans, however, she may have been mistaken, as no laboratory of the reshapers have been discovered yet currently in New Britannia, that have evidence they were created in such facilities from humans.
 * And always the Fomorians, remnants from the Dark Armies of wars past threaten; from their strongholds in Blackblade Pass they often strike looking for prey.
