Freedom City - New Freedom League Ascendent
Earth's Master Mage
Detailed in Freedom City version 2, pg 139
Earth’s Master Mage is terribly mysterious.
He keeps to himself in a brownstone on Ditko Street in Riverside, perched atop a dimensional nexus. As the Master Mage, it is Eldrich’s responsibility to defend Earth from great magical threats and demonic incursions. To this end, he prefers to remain at his home watching rather than solving small problems. He is willing to provide magical assistance to his allies when needed, though.
During Freedom League Rescue, Eldrich helped the heroes travel across the Galaxy to The Citadel, by opening a portal to a shifting dimensional plane, that carried the heroes across the light years in no time.
