セレナ・オペコット

While growing up in an orphanage, she dedicated herself to the prominent religion of the region which worships the goddess Sharia. She survived a ritual which turned her into a Saint who can turn prayers into powerful light and healing magic.

She and Lucina share the same mother but her father was a sick prince of another country. She was orphaned after the father's death when also her sick mother was sent as supposed sacrifice to the demon lord. 

Knowing of her origins but unaware that in fact her mother was never and is still not being held hostage, she enters the labyrinth in order to defeat her sister, for her mother and for peace./
