Ancient One

The entity: Former Sorcerer Supreme of the Earth dimension and master to Doctor Strange. He is now "one with the universe", a form of benevolent spiritual entity.
The spells: "By the power of the Ancient One". Used as a supportive incantation. When used with a "white" school magic spell for the furthering of order it adds a bonus of +2CS for all FEAT rolls related to the spell. This can only be used once a day by a player character. Clea can use it up to 4 times daily and Doctor Strange can use it whenever he wishes.

Though the Ancient One, like Gaea/Mother Nature, exists in the Earth dimension his power and influence is so great (and his response to entreaties are so like an entity) that he is considered a dimensional entreaty power for the purpose of the game.
