There are other benefits, none of which she has enjoyed because she has been the only one in her Pantheon. So she is not losing much by giving up on it. What she cares about more than her Pantheon is the ability to acquire a domain. It is after all what every god came to this world to acquire. If she can't get it, then she is willing to lose her last Oracle now and try to find another means of survival.
Legion considered the question and replied, "You can become a domain god anytime you want. The 9 Crowns won't ask you to limit your growth. But you have to tell him when you acquire information about a domain and you have to sell any extra domain you have to him."
She replied, "Alright. I have disbanded my Pantheon. I will await the 9 Crowns request to join his Pantheon."
Their faces fell as they said, "Don't lie to us. You haven't disbanded your Pantheon."
She insisted, "I have."
