The Blue Knight is a large and stout knight wearing heavy plate armour coated in blue enamel. He has a full, red beard and twinkling eyes, and he is given to loud bellylaughs.His shield is also blue, emblazoned with the four eyes of Terminus.
The Blue Knight visited Baronet Francois in early Yule 6588, after he had slain the dragon. He gave the knight a ring of four metals, set with four intaglios, which Francois has carried since. He also gave him some rather cryptic advice.
Artois LeBrave (and Bimle?) seem to be connected with the Blue Knight, somehow, as Artois has an extremely similar ring, and spoke privately with the Baronet about the Knight.
