Thea was Lady Holder of High Reaches Hold late in the First Interval and early in the Second Pass. Her spouse was Lord Holder Jamson.
Since Jamson was determined to be too ill to be involved with the impeachment of Lord Holder Chalkin, Thea and her oldest son Gallian sent Jamson to stay at Ista Hold so that Gallian could take his father's place in voting for Chalkin's impeachment.
