Hexfane

Hexfane is the god of decay, poison, deceit, disease, starvation, and getting lost. His depiction in myth varies widely. Usually male, but he is sometimes depicted as female. He is sometimes called the "Second" Lord of Hate, and is known for avoiding attention to operate in secret.

Mount Hexfane is also the southernmost volcano in Haelfaun. The god Hexfane is bound here, hence the volcano takes his name. The volcano's ancient Cayrien name is Arcanion. At the beginning of the series, the volcano is dormant, but it begins smoldering in Book 2. It never becomes fully active, but continues to smolder throughout the series, until Hexfane's defeat in Book 9.

The ga'arg call Hexfane Haethen, which very roughly translates to "mortality," or the idea that life is limited and death comes for all -- a comforting notion to ga'arg.

Vassal: In later books, Hexfane pursues High Raven Itaebi Fellstaff, seeking to co-opt her as a kin vassal. Itaebi remains loyal to kin, and Hexfane chooses another (yet undetermined) person as vassal.

Agenda: Hexfane's primary focus is retrieving the Sky Key and delivering it to the Dream to release Althuzah. He also works to create chaos, discord, and strife among the man-kin nations of Landfall. Hexfane plays a major role in the political intrigue of the Jeceau Civil War.

Ghuul: Ga'arg who pledge to Hexfane become mor'ghuul. The most recognizable mor'ghuul are undead, particularly waterlogged corpses and spirits of the countless hundreds of thousands (or even millions) of man-kin who drowned at the dawn of Water's Age.

Poisonous snakes, river snakes, and maggots are also said to be agents of Hexfane.
