Ethsharitic religion is polytheist, but no one has a full list of every god. Nobody claims to know who all the gods are, or even how many there are. Priests and theurgists will generally develop relationships with a certain selection, either ones they were introduced to by their masters during apprenticeship, or ones they've come across on their own, one way or another. People other than priests tend to pray rather non-specifically-- "To whatever gods may hear" in hopes of increasing their chance of being heard by any god who might care. Some people will latch onto a particular deity or a specific shrine, but most prefer to mind their own business and let the gods mind theirs.
There's no ruling hierarchy of gods. Some are obviously more important than others, but there's no king or queen, no central triad; the gods are assumed to be anarchists. After all, since they're incapable of evil, they have no use for law enforcement; they don't need public works; with certain peculiar exceptions they don't use money, so they don't have taxes or coinage or tariffs; they conduct no trade, so they don't need regulations. The Ethsharites just don't see any reason gods would need a government.
In practice, the gods are seen as well-intentioned, but detached and whimsical, with little understanding of mortal existence. There's also the known fact that any time you talk to the gods there's a good chance demons will listen in. Dealing with gods is therefore seen as something best left to the experts, i.e., priests and theurgists.
