In the mythological writings of William Blake, Tharmas is one of the four Zoas, who were created when Albion, the primordial man, was divided fourfold. He represents sensation, and his female counterpart is Enion, who represents sexual urges. He is connected to the God the Father aspect of the Christian Trinity and is the begetter of Los. Tharmas is mostly peaceful, and flees during most of his fights with Urizen. He is depicted in various ways ranging from a youth with wings to an old bearded man.
Tharmas is both the last Zoas described but also the first in the number. As a body part, he is the loins with his Emanation/mate Enion representing sexual urges. He is also represented as a shepherd. Tharmas is connected to the direction point West and his fallen state is to mark the Circumference of the world. His elemental connection is to water and, in turn, to time. His artistic aspect is Painting and his particular sense is Tongue, which represents taste and speech. He represents both free speech but also false speech. In his divine state, Tharmas is peaceful and idyllic. However, during the war among the Zoas, he fights until he is defeated and falls. His name is possibly a back formation from their daughter's name, Enitharmon. Tharmas is the unifier of the Four Zoas. When Tharmas vanishes, he is replaced by chaotic nature.
Tharmas was introduced during the 2014 Kappa and the Lost Utopia event alongside Albion and the three other Zoa. He can be fused by players with the Zoas plugin through a special double fusion of Sudama and Aquans. Like Albion and the others, he possesses a feature called Milton, which gives him 100% elemental resistance according to which Zoa are in the party. After Mitama fusion, he gains another feature called Bunrei (分霊, lit. Divided Spirit) which increases his elemental damage by 50% according to which Zoa are in the party.
