Clovis

Clovis, also known as the "Prince/Princess of Thieves", is a Keidran and leader of a black market magic guild. He appears as the main antagonist in The Dragon Masquerade.

Background
Clovis is revealed to be the one who saved Natani's soul after the siblings botched an assassination on the deadly sorcerer Issac. Since then, he has tried many times over six months to get the siblings to repay him by doing several actions.

The Dragon Masquerade
He informs the duo, by mental link, of their roles and job of securing the flawless mana crystal in the Dragon Façade mask during Dragon Masquerade. Before leaving Zen, he "motivates" him by saying he would expose Natani's gender to the guild, should they fail. Clovis would watch Zen and Natani as they continued on the heist.

He would later discover that Natani has broken the agreement with him, and decided to save her brother in exchange for the mask. Furious, Clovis uses his magic to try and control Natani's body. Despite this, Natani is able to give the mask to Saria to complete her contract with Nora. Clovis berates Natani and tells her he will tell the guild of her gender, and make her suffer. Lady Nora, listening in by joining the mental link, decides to punish Clovis for his actions by turning him into a woman. Nora muses Clovis on his new appearance, with Clovis retorting that she won't get away with this, right before being kicked out of the mental link by her.

After his transformation and disconnection from the mental link, Clovis has stopped bothering the siblings and has retreated outside of most public life, fearing if his secret be revealed.

Personality
Clovis is a vain man, who enjoys holding control over other people. He holds an irrational hatred to women, due to his half fox heritage from his mother and the wolven view of foxes as lower class citizens. He is also shown to not care about people and views them as expendable, as he didn't hesitate or care that Zen was captured by Lady Nora.

Trivia

 * It is unknown if Nora's magic on him is just temporary like Mike's encounter, or perfect transformation like Euchre.
