Zaghnal the Wraith-sickle

Zaghnal the Wraith-sickle (Nameless):  The first Nocturn to meet the heroes in the stories. It possesses Mrs. Case and is the main antagonist of the second book. Zaghnal has the group nearly defeated when Mr. Jones shows up and reveals some insights about the Nocturns. Zaghnal’s nickname is “Nameless” because its weakness is found in its name. Once its adversaries/host knows its true name, it can be weakened to the point of exorcism and eventual banishment back to The Void. Its weaponry consists of two, flesh-tearing scythes for hands that reform after destruction. It can also use dark energy to stun opponents. When it possesses Mrs. Case, it has use of her Talisman, Fujin’s Teardrop, and can ride air currents and use wind blasts. Zaghnal is defeated and exiled back to The Void in book 2.

Trivia: Mr. Jones finds Zaghnal's weakness inside one of the red books that the heroes have. Since they have been reincarnated many times over the years, most Nocturn's are described and documented in these books to assist future generations exorcise them from human hosts.
