The Tarim church teaches that the great war was a result of a nation of powerful but reckless magi who opened a portal to a demon plane. As the traditional gods of the old world where unable to conquer the threats unleashed, the One True God stepped forward, leading his champion, Lucius Tarim, to victory over the hellspawn and their mage slaves. Tarim therefore takes a strongly anti-arcane magic stance. They have gained significant influence on the continent of Mir in the few centuries since the war.
Non-believers are not as keen on Tarim’s version of events.
