Konnichiwa Maciamo-san!

Don't think by All or Nothing. Of course traveler pray to traveller's god. But it don't means main worship to traveller's god. If traveler is hunter, his main god is Artemis. Even he pray to traveller's god, it don't means give up his faith to Artemis.
If one change his main god frequently, it is not religious faith. It is a magic worship. All people can pray to god even one is not believer.
