Gundred is the oldest daughter of Lord Barak and Lady Merel of Trellheim. Her estimated birth year is 5361-5363. She is described "only slightly older than Errand" (Castle of Wizardry) with long reddish-blond braids. She is a year or so older than her sister, Terzie.
By the time of the birth of Geran, she is described as a ravishing young lady who attracted many-a Rivan noble. (Barak was in the background with a watchful eye and didn't tolerate any foolishness.)
