Siff Duthar was a necromancer who lived during the Age of Arcanum. He experimented with binding undead souls to the physical remains of bodies, eventually performing the process on himself when he became an allip.


In his allip form, Stiff Durthar was semi-corporeal with the lower half of his body tapered off into nothingness[2], as the mass of his head and body were centralized in a horrible whipping swirl of localized wind, shadow energy, and tendrils of cloth from the four to five layers of shredded robes and the tattered cloak he wore.[3] The physical touch of his form felt almost like touching heavy, cold cloth.[4]

Hidden in the center of this swirl was a dull cold blue heartbeat-like[5] glowing source of energy.[6] His ghastly visage was of dark grey flesh stretched against the skull that shifted along with its spectral shadowy form.[7] His eyes were vacant sockets that slowly billowed out smoke.[8]


Entries from the Notebook

Siff attempted to destroy all of his works, but some of his writings were salvaged when one of his notebooks, although heavily burned in one of its corners, was spared destruction when it fell out its brazier to come to rest underneath one of the tables.[9] Written in Draconic, this book contained the disjointed scribbling of his thoughts, experiments, and fears.[10]

The ramblings within this book spoke of a coming war. He described foolish pawns who followed their gods to annihilation. He spoke of the armies of Ghor Dranas washing over the land and paupers and kings alike not finding salvation, but instead being placed on pikes and held like banners into battle regardless of who they are. The book spoke of the weakness of flesh and the need to endure beyond the paltry life shell that one was given. It talked about his experiments on refugees, and his search to see if the soul could be bound to flesh of any form, be it ice or ash. It spoke of an obsession with avoiding the eternal hunger of The Crawling King, he who tunnels beneath the world and would find him.[11]

It spoke of a bounty hunter who had infiltrated his sanctum in search of him, and although his battle with him cost Siff his legs, the bounty hunter was burned in the flames of erasure, and his greatsword was taken as a trophy and mounted above the back bookcase of the research chamber.

"A trophy shall be taken and displayed as a warning."
Siff Duthar's journal

Becoming more manic as the journal went on, he spoke of the coming of the Betrayer Gods, and how the earth shook around the surrounding hills, and how the skies had grown dark. He wrote that the power of man must remain, and how his arcane gifts must bypass their punishment, to show them that they are not above their creations.

In the final notes of this book, before it became charred beyond recognition, he grew even more paranoid and worried that his secrets and research would fall into the hands of Ghor Dranas, and to prevent that all of his work must be destroyed.

"All must come to ash and from the ashes, shall rise again."
The final page of Siff Duthar's journal[12]

Interaction with the Mighty Nein

Having bound his soul within a large urn located behind the back bookcase, Siff was able to return after death[13] and appeared to the Mighty Nein as an allip when they investigated his research chamber. After being first defeated by the party, he returned again, but was finally, with an almost sad expression, destroyed by Molly who managed to break his urn, thus banishing him from the Material Plane.[14]
