Matron Theresa is guardian of he Mercia Orphanage.

She has been running the orphanage since the Hundred Days War when she took in a young Kloe, whom she and her husband Joseph raised as their own daughter. Even though her husband passed away years ago, she has continued to take in more children and keep their legacy going. Thankfully, she has help from Kloe, who still returns to visit and help out, as well as many inhabitants of the Village of Manoria.

Currently, she takes care of Clem, Daniel, Mary, and Polly.
