Little is known of the Historian of Ossus, besides his famed Commentaries, which survives largely intact. His greatest work, The Fragmentation of the Imperium, itself exists in fragments only. Other historians have put forth the case that much of his writing draws from another great work, The Latter Onderon Dynasties, which has sadly perished. He maintains a studied distance from Revanant revisionists, using the more archaic descriptor "barbarian" in his narratives on the emergence of the Revenant; he retains the ancient Jedi prejudice towards the Sith.
