Gosselevism is a branch of Adanism which formed in the 7th century in Goscelebe, in the Orthodox Empire of Arpenea. Gosselevism rejects several core features of mainstream Adanism, believing that they were not original to the words of the prophet Adanōs: first, Gosselevites reject the doctrine of dualism, believing that The God is rather singular, whole, and indivisible. Consequently, most Gosselevites reject the doctrines of Eleia, the divine and continual grace which instilled Adanōs and instills the Saints, and the doctrine of Mesdouro, in which worldly evil was a separated creation of the God. Therefore, most Gosselevites do not believe in Saints, believing instead that Adanōs was singular and unique before the God, and in some cases, himself the God in totality. Some Gosselevites, particularly ‘Continualist’ Gosselevites, believe that the God continued to bless Saints.
Arpenean rule was greatly damaged by the conversion of many of its southern nobles away from the faith of Tanthes, and Orthodox rulers were encouraged by Tanthes and Imperial Panarine to censure this move. Even in the Orthodox stronghold provinces of Tarheny and Aalmergrafe, Orthodox rule was nearly diminished. The modern state of Almeria exists solely due to the intervention of Orthodox Tanthene northerners, including a great many holy warriors sent to reestablish the Orthodoxy in Arpenea. In centuries of war, Orthodoxy could not be reestablished in the vicinity of Goscelebe, Kandergrafe, Daartlaw, and other southern lands.
