I'm probably the only one but I've never considered the gods of Thera to be omnipotent at all. I've always approached it as using examples from other religions that have had a pantheon of gods rather than a single one omnipresent deity.

In Greek and Roman mythology the gods were not omnipotent. They didn't know everything. And you could sneak stuff past them almost all the time. Sure they would find out eventually but that's because the gods always had agents/allies/etc who would pass along information to them.

An example of this would be when Hades kidnapped Persephone and her mother, Demeter, had to search for her daughter because she didn't know where she was. When she couldn't find her she made all the crops dry up and Zeus was the one who had to go find her.

But that's just me. So I guess if people look at it from that perspective then it makes sense that your god may not know who you are until they actually meet you. And you can use notes/email to coordinate this.

EDIT: Additionally if you read the mythology of CF you'll see that this perspective is how you should look at it. Especially when the IMMs run easter egg hunts.

"I am an omnipotent god that knows all and sees all.... now where'd my eggs go?"
