Taking from the comment from the post, if they are Greek based (speculatively) There could be not only temples but shrines. Small villages (maybe nomads Elveens) with portable shrines or set stones where rituals and such can be made. Probably seasonal routes leading to shrines where events will be placed. . . pretty much like FFX where some temples were elaborated and others were even forgotten yet everyone recognized the "all summons" but not everyone prayed to all or the same one.
