Many deities are worshiped in association with other deities. That associated deity (and often their priests and initiates) is present and participate in the primary deities rites and secrets. For example. Ernalda’s husband deity participates in many of her mysteries – Orlanth in Sartar, Yelm in parts of Saird, etc. The Orlanth initiates gain access to some of Ernalda’s magic (but using Orlanth’s Rune points) and Ernalda gets their sacrifices and magic points.Orlanth and Ernalda have plenty of associated gods, and if you put together the web of associations, plus a few other friendly (but autonomous) deities like Humakt, you have a local pantheon of more than two dozen deities. Even if you are an Issaries initiate, you still typically participate in Orlanth rituals; if you are a Maran Gor cultist, you participate in Ernalda rituals. Yelm also has plenty of associates, and you can quickly see the web of the Solar pantheon, centered on Yelm, but with smaller webs extending from Lodril, Dendara, and Dayzatar.
For example, The Red Emperor is the supreme head of the Yelm Imperator cult though and Yelm is an associated cult of the Red Goddess, which means that through the Red Emperor the Lunar gods and the Solar gods are united.
Deezola is associated with Dendara. And Hon-eel is associated with Dendara and the Grain Goddess, but not with Ernalda.
