Sir Isembard is a distant cousin of Duke Thierry and has used his status and family connections as a cudgel to get away with all manner of dastardly deeds. He may have finally gone too far, however—his wife, Lady Bertha, has disappeared, and rumor has it that Sir Isembard has either killed her or had her thrown in a dungeon! The fiend!

He made his home at the manor of St. Hubertus. In 769, he was defeated in combat by Sir Pippin and swore an oath before the King to undertake a pilgrimage to the Holy Land. Before he could depart, however, he was slain by Sir Girart, acting in vengeance at the behest of an unknown friend of Berthe’s.
