Before Gods took names they existed at the edge of understanding, In the early days of culture and language, as animism shifted to worship, Gods were not always named. Some of these nameless things retain enough worship to still exist today, and psychonauts are warned to speak to reverently or make statements appearing too much like generic prayer. Stray words can provoke a nameless god to answer an unattributed prayer and then demand payment.
Every now and then, a Nameless God will acquire a voluntary worshiper or even a cult. And even more rarely a Nameless God will acquire a name and enter the ranks of the Named Gods.
