Larm was an admiral in the Imperial Navy who was in charge of forces in the Antemeridian sector under Moff Getelles. Larm was a by-the-book sycophant who ingratiated himself with Moffs while never relaxing his warrior image. Getelles promoted Larm to admiral over the heads of several other officers shortly after his promotion to Moff of Antemeridian Sector. Larm was seen as a sternly efficient foil to Getelles's fair command style.
