Atheism is a philosophy on Kishar that rejects the worship of any divine being or object. This could involve simply not believing any such entity to exist, or that entities called gods by others exist but are only powerful magical creatures, or that deities do truly exist yet are not worthy of worship.
Atheism is relatively uncommon on Kishar - those who find themselves drawn away from deities, or who live in cultures that traditionally lack them, more typically worship nature spirits or their ancestors instead. Still, it is not entirely unknown. In at least one nation, Vothan, atheism is the official philosophy of the state, even if it has not taken root amongst the common people.
