Harry Dresden describes him as basically humanoid, gaunt, skeletal, and grey-skinned. He has curved, very pointy spurs of bone jutting out from every joint. His hair was greasy and lanky hanging from his knobby skull. He has two pairs of eyes: the human pair were brown, the demon pair were glowing green. He wore a heavy canvas messenger bag across his shoulder.
At the end of Small Favor, Sanya says that the coin was not with Michael when he came off the Helicopter. Harry goes to talk to Marcone about it. Marcone knows nothing of the coin, but says he will make inquiries. Harry wonders if Gard has the coin.
Thorned Namshiel is a powerful and skilled wizard. Among the spells he's shown are: shooting sickly green lightning, generating gusts of wind, and summoning black, magic-disrupting threads.(reference needed) He also demonstrated the ability to manifest sickly green threads that he can manipulate. He was able to alter the magical wavelengths of these threads so that Harry's shield couldn't stretch its magical wavelength to stop them all.(reference needed) Thorned Namshiel also has the ability to shoot spines from his body.(reference needed)
His skills are a century or two ahead of that of Harry Dresden as evidenced by his design of a flawless Empowered Circle that could tap into a dark ley line to contain the Archive. His raw power allows him to call up Hellfire enough to burn through the defenders of Arctis Tor, calling forth massive amounts of heat in the heart of Winter.
In the seriesEdit
- Main article: Small Favor
In Small Favor, as Harry rushes into the Shedd Aquarium to try and save Ivy from the Denarians, he nearly bumps into Thorned crouched on the floor under a veil working a spell. Harry disrupts his circle and flings the skull cup into a huge tank. The Denarian ate the force spell Harry threw at him. Then Thorned conjured a smoky prison from black threads he spewed from his mouth landing all around Harry. The prison-spell shatters Harry's shield and blocks all of his magic. — Some unknown power creates a silver hand construct for Harry, floating away from him and reflecting his movements. It breaks the prison and thrashes Thorny through several walls and glass ripping him to shreads, but not killing him.
Later, he is waiting with the other Denarians at the top of the island (later to be named Demonreach). His maimed body stretched on the ground. Fighting breaks out, the Denarians scatter, he's stuck on the ground, begging his pals Tessa and Rosanna to come back. He throws green threads of light at Harry, one wraps around Harry's neck, choking him. Michael lops off his head, then cuts off his hand with the Denarian Coin in it.
When Harry encounters Nicodemus at the boat, he demads the coins. Harry no longer has the bag of coins, it's gone. Nicodemus deduces that it was Thorned that took the coins while he was strangling Harry by the marks on Harry's neck. Thorned had done that to some saint in the thirteenth century Glasgow.
Near the end of Small Favor, Mab says that she and the Archangel Uriel had a common enemy that day, that there was one among the Fallen who had to answer for the Hellfire attack on Arctis Tor. Harry remembers the silvery hand and infers that Mab means Black Council and Thorned Namshiel.
