[edit] Guild of Heroes
In the GoH storyline Theresa is introduced as Sabre's younger sister. At first she doesn't get along with any of the other trainees, but eventually gets used to their antics. She develops a relationship with Arkhos after a rather awkward and embarrassing moment designed by Ladron to drive them apart. She dies during the Epilogue due to complications when giving birth to Jennifer.
