Background[ | ]

Fidelitas was once a slave named Raulo.[1] He fell in love with Maligaro, who later demonstrated his new skill at imbuing humans with the calibric extantia on him. It is not clear if he liked this gift,[2] but he remained loyal to him. To honour this fidelity, the monster he had become was named Fidelitas.[1]
