What is known
S9The Lion historian at the Hall of Scribes. His account of the Battle of the Snow Plain gives the victory to the Unicorn and never mentions the Scorpion at all. The records themselves are partly lost and partly never deposited. Young Lion samurai in the room did not take the recital well.
S19Went into the genealogies himself and could not find a man his own clan's rosters praise.
S21Holds that acknowledging the Empire's intervention at the Snow Plain, rather than declaring a victor, would settle rather than inflame. Produced a young Kitsu's documents on the Lion's supply failures — unexpected early-season snow, and shortages beyond it. He named third-party interference without naming the third party.
S25Authenticated the Imperial-Sealed Official Treaty, which validates the Unicorn claim to the Snow Plain. Found that the signed secret agreement carries no Imperial seal, and that the "least of the Bayushi" clause is too vague to bind. Confirmed the cache scrolls genuine against library samples. Confirmed no secret treaty is on file anywhere — and that the Shinjo Kamo Letters vanished overnight after Monban's late visit.
