Zoth-Ommog is an ancient and demonic god that exists outside reality and seeks to enter our world. To accomplish this, he took a virgin to be his "bride" in order to reincarnate a portion of himself into the mortal realm. This mortal would be inseminated with a piece of Zoth's power in order to produce a child.This prophecy would eventually break down the barriers between realities that would eventually lead to both realms becoming one.
This dark Messianic figure would go on to begin the process of combining both worlds, but would eventually leave this reality, leaving the unfinished work to his followers. The religion that developed around this god is well aware of this truth, and how this prophecy involved three individuals: Zoth, the mortal bride, and the product of their union. However, instead of worshipping these three beings as separate gods, I would like this faith to go on to worship this trinity as one being, similar to the blessed trinity in Christendom. How can I ensure that this outcome is possible?
