You are the Hierophant, the only one who is capable of serving as the facilitator of communion between heaven and earth. You are not just the chosen champion of any single god or pantheon, but rather the chosen champion of faith and worship itself to herald in a new age of god.
Your ability to work divine magic is second to none, but the gods themselves and even lesser deities find it hard to compete with you due to your ability to effortlessly tap into the various authority, domains, and symbology of different gods and pantheons to work your magic. Over time, your mastery of divine power could grow to rival that of the chief god of the Renown Pantheon.
As faith and worship of the gods increase, so does the strength of their influence on the world. The gods are somewhat obligated to grant you what you ask for, but the greater the act you wish the gods to perform, the greater the required faith, worship, or specific conditions must be met.
As the Hierophant, you are not the slave of the gods but rather the mediator and reconciler between the divine realms and the mortal plane; thus, you can cut the connection between specific gods or pantheons from influencing the world if you choose to do so.
