Divine Sense!
The origin of the summoned presence within the sacred ground became immediately apparent to Eren. His past experiences with the Slumbering Goddess hiding within Sienna Slughorn had provided insight into the nature of Divine Sense—a power exclusive to divine entities.
Even in its most modest form, Divine Sense held the power to ward off the consciousness of worlds to some extent. It allowed divine beings to exert a fraction of their power in the various realms their consciousness traversed.
Moreover, it possessed the capability to establish an Authority Domain, carving out a separate realm within the world into which their consciousness was pulled, enabling them to somewhat explore the given world through diverse means. Utilizing Sienna Slughorn as her vessel, the Slumbering Goddess had extended her Divine Sense across the lands of Anfang, imprinting her presence.
