Catrinna Gyre was the wife of Duke Regnus Gyre and mother of Logan Gyre.
Catrinna Gyre was born into the ducal family the Graesins, before Terah Graesin rose to power, though her position in the family is unknown.
She was a strong and intelligent woman. She attempted to gain control over Logan on occasions. First, she tried to outrank him when Solon Tofusin first came to their estate. Then she went to the queen to attempt to gain guardianship, which would put her in power over Logan.
