Khaevis

Background story: Khaevis was unfortunate to become the pawn of kingdom of Aurea. To elaborate, its first king led a futile attack against her where he and his forces could only managed to destroy her eggs, culminating to her coercing his family to sacrifice their three daughters each generation. While it appeared kingdom of Aurea agreed with such pact and upheld it for generations, the kingdom abused a loophole where they instead offered random would-be princesses marked with their blood.

Personality: While seemingly a sadistic and malevolent entity, Elodie soon learned that Khaevis is more of bitter and misunderstood dragoness as she had lost her beloved daughters and did what she did to punish the kingdom of Aurea. But unfortunately, the kin of her daughter's murderers were too treacherous and unrepentant to take responsibilities for their actions. She also appeared to draw the line of attacking younger members of other species judging from hesitation in attacking Floria.

Although Khaevis and Elodie ended up on each other's throats because of royal families of Aurea's machinations and the former killed her father, Khaevis ultimately put aside their difference in order to face the ones who are responsible for the predicament in the end, showing that she could still be reasoned. When Elodie told Khaevis the truth about how she has been tricked in the deal, she denied it as a lie. When Khaevis refused to listen Elodie decided to showed her the mark of the blood ritual. This revelation made Khaevis understand that she's monstrous as the royal family for massacring innocent dames just like they have. Because of this she allowed Elodie to end her life to end the madness. But Elodie spares her and heals her using her cave's resident glowworms so that they can both take down their mutual enemy.

In the novelization, the relationship between Elodie and Khaevis runs deeper in the end of the story; when Elodie wounds and then plunges her sword into the dragon's heart while trying to rescue her sister, Floria, Khaevis likewise mortally wounds Elodie. But the glowworms Elodie swallowed earlier in their confrontation heal her wounds, and Elodie's blood mixes with Khaevis'. As a result, both are brought back to life, but with Elodie becoming able to transform into a dragon three times her human size, and Khaevis not only being healed but becoming able to lay eggs again as a result of their magical connection.

Physical appearance: Khaevis is a large, slender, quite muscular dragoness with brown and dark green scales, a long tail and large, leathery bat-like wings. She also has glowing yellow eyes and robust-looking necks which gaps between scales shone in neon yellow whenever she breathes fire.
