Long greying black hair usually tied back in some way to display the Haltija symbol on her neck. She is always dressed in fine gowns and has a stern expression on her face. When she speaks, it is with purpose.

Katalina is Seneschal of Seshtau and an Elder Haltija. She came to Ariad around the time Necromancy became legal in Ariad and with the help of the previous Baroness, Eclipse, has created a sanctuary for her people who are hunted in their homeland. The current Baroness, Jade, is one of her students and she has a son, Julien Mesen'ke, who has recently returned to Ariad after an adventure in Leib Olmai.
