Tales of the Traveler
The exact nature of the Gods is unclear, and students of the Arcane have dedicated libraries’ worth of debate to the subject.
Some argue that the Gods owe their very existence to Mortal belief—that the Primary Gods are the most powerful because they have the most worshippers, rather than the opposite. Indeed, there are undeniably cases in which Gods have come into literal being as a result of mortal worship, as in the bizarre case of Gold. Some scholars go so far as to speculate that absolutely anything that anyone anywhere believes in exists in some form in the Outer Heavens.
On the other hand, many of the Gods seem to exist independently of Mortal belief. An example is the Goddess Brusha: though forgotten for thousands of years, she appeared to have lost none of her potency when rediscovered by Elven researchers. A popular explanation is that those of the Gods who do not depend on Mortal belief are the anthromorphic personifications of concepts that exist intrinsically, while the others represent ideals unique to Mortals.
