The Elder of the Hexen Clan
She may have the appearance of a young girl, but her true age is somewhere over 800 years old.
Though the three are not blood related, Roselia is a grandmother to both Emma and Vita, as well as their master in the magical arts.
As new Class VII went about performing their field exercises, Roselia appeared before Rean a number of times, leaving cryptic messages for the Ashen Awakener.
During the crisis in Heimdallr, she joined forces with Thomas Lysander of the Gralsritter to aid Class VII in trying to prevent the curse.
