Tescovax

Tescovax was the dragon cursed by having his heart removed that asked Mari to be killed while she scried on it. It appears as a living dead dragon with its skin flaking off. His name was learned by asking the talking head.

Mari researched Tescovax in the library at the magic school. One book merely mentions "Tescovax the Kindheart" as having been a very foolish lord. There were several other mentions of the name in historical texts but they were mostly just lists of names that teach that he was likely a silver dragon. Another book, "The folly of Kindheart", is a children's book that tells the tale of a kind hearted lord clad head to toe in silver threaded clothing. He was kind and honest to a fault, and for this, his subjects loved him. Throughout the tale, his kindness often causes him to be used by those closest to him, but he does not retaliate except by weeping openly in front of those who have wronged him. The book describes his tears being so powerful that the wicked would repent before him and confess their wrongdoings. One such occasion caught the attention of a nearby lord clad all in copper, who introduces the kind lord to his daughter, a beautiful lady in red. The kind hearted lord is immediately smitten by her charms, and a match was made, but it was all a deception in the end. The lady in red was actually the wife of the copper lord and together they plotted against the kind heart, to steal his lands and subjects. The kind hearted lord was led away from his lands to honeymoon in a hidden glade among the wildwoods, from where he never returned. In the end, the lady in red stole more than his heart, and offered it all to the copper lord.
