Heroldar is an Imperial stronghold of the Thramas region (the Eastern Fringe of the Segmentum Ultima near the old Nostramo sector), against which Horus, after Isstvan V, sent the Night Lords with Titans of Legio Ulricon; Curze’s genocidal campaign passed through the systems of Heroldar and Thramas (c. 007–009.M31).
