A living eye tattoo over Carl's sternum permanently embeds Shi Maria within him until he chooses to keep her power or set her free.
Shi Maria uses toraline ink and Li Jun's blood to rapidly tattoo a small eye into the center of Carl's chest. She says the dangerous spell may carry a trace of Li Jun's powers and will teach Carl how to wield strength sufficient to become a god.
Her purpose is to attach herself to something Carl cannot discard like a card. He must eventually choose to keep her and gain her power or release her; Shi Maria considers either outcome a victory.
When the fusion ends, the bloody eye blinks, closes, and disappears against Carl's skin. He still feels a bottomless hole inside. The interface gives only the tattoo's name and no description.

The Eye transforms Shi Maria from a removable deck threat into a persistent internal presence and unknown power source.
