A few examples of how cults are spread across space and how that is experienced by members of the cult.
1. Orlanth. Vasana was initiated into the cult of Orlanth Adventurous (Vinga) at the major temple of the Colymar tribe (as is common). As an initiate she offers worship to Orlanth at all sorts of temples and shrines to the god and his aspects throughout Dragon Pass, Pavis, and the Holy Country. Vasana has traveled from Clearwine to Ralios and had no trouble offering sacrifices to Orlanth in the countless temples and shrines to the god along the way. Normally she recognises the regalia, the accoutrements, and the songs in Storm Speech – this stuff has been carried throughout Genertela over the last sixteen centuries.
2. Odayla. Nathem was initiated into the Bear God cult in Old Tarsh. There is little more than a few shrines to Odayla there, and Nathem wanders widely offering worship to the Sky Bear wherever he can. He travels to Sylila where there is a large and organised cult with as many people as the entire adult population of the Tarsh Exiles. It is an eye-opener, with new stories, new myths, and more. So Nathem keeps wandering, and eventually makes his way to Fronela. There he encounters the Rathor cult – and Nathem tries worship the Great Brown Bear there. Does he succeed or is that the point where the differences are too great? Dunno, sounds like a fun part of that campaign though!
3. Yelmalio. Berensor was initiated into the Elmal cult at Famegrave, where there was a minor temple. He got caught up in the Elmal cult’s conflict with the Local tribal leaders and the Sartar Dynasty, and was exiled for kinslaughter. He went to the new Sun Dome Temple in the Amber Fields and of course recognized the Elmal stuff other exiles had gathered there – and he offered worship there, and of course it was successful (he regained his Rune Points!). He swore loyalty to the Major Temple to Yelmalio there and was rewarded with a plot of land, a spear and some armor. He fought for the Sun Dome Temple against the trolls of Troll Woods, and eventually became a Light Son.
Berensor died at Grizzly Peak, fighting for King Tarkalor and the Feathered Horse Queen, along with many other Yelmalio cultists. His grandson Varthanic was initiated into the Yelmalio cult at the Sun Dome Temple. He’s traveled to Prax and worshiped Yelmalio at the Sun Dome Temple there, although he found the Sun Dome cultists there to be quite backwards and extremely provincial, although the beer was excellent.
Varthanic later traveled to Mirin’s Cross, and was struck how the Sun Dome Temples maintain their identity despite the Yelm nobles from the Heartlands. The Lunar influence troubled him, and he was surprised at the semantic games the Light Priests used to avoid acknowledging Lunar hegemony. Nonetheless, the Sairdite temples had many new stories and myths. From there Varthanic went on to the Hill of Gold, where he walked those sacred grounds.
