Lord Hazkrakor

Lord Hazkrakor is a Silver Dragon who was the first lieutenant recruited by the Vampire King Alyssa. They are the only Dragon ever to serve as a lieutenant long term.
Hazkrakor and Alyssa have a "platonic prince charming" relationship, in which Hazkrakor ironically plays up theit politeness and effervescent praise and she plays up her being a nine-year-old girl, even though she's made of stone and also a millenia-old vampire. They (collective) treat it as a weird game.
They also possess a possibly-intelligent magic sword (almost certainly an artefact) called Eclipse, which was forged during the long night brought about by Pelor's death "by beings of feverish intellect and foresight". (Rahjs?) Haz found it before they met Alyssa, but it was only with Alyssa's aid that they could wield it without "becomming its pawn".
