Theresa, The founder of Babel.

The former King, of all Sarkaz.
Omg it's the woman who died, but not really

After the events of Chapter 14, Instead of Theresa disappearing without a trace, she left behind an Originium crystal upon her departure, after a battery of tests, Rhodes Island found out it was... Theresa's consciousness within the crystal.

btw this is my way of bringing the actual Theresa back, cause Civilight Eterna is TRASH.
