Vain is the master of Mischa, a cat familiar. Vain is Hugo’s older brother, and like Hugo, Vain also is from the future. Vain also gives Hugo missions to complete in order to prevent the Dragonkins from ending the world. It seems that Vain is a messenger that serves under some higher power. That power is the one that assigns Hugo on certain missions, and Vain's duty is to report him of these changes. He also watches Hugo from afar to make sure that he is properly carrying out his duties.

Vain will not hesitate to interfere with the protagonist if she is digging around too much for information. However, he will only answer what she wants to know. If she asks questions that do not relate to what she wants to know, Vain will silence her by preventing her from asking further questions. He finds the protagonist to be a bit troublesome. At one point, he even goes as far as threatening to stop her heart beat so that she cannot argue with him. 

Vain is most definitely not as nice or understanding as Hugo. He is a bit cold-hearted, selfish, and very secretive. He will not hesitate to get his hands dirty. Vain is also a bit rude, calling the protagonist a shrew that Hugo has to control. He definitely has the type of personality that would cause him to have many enemies.

Voice: Any pitch, mysterious. Maybe also a bit gruff, cold, or intimidating sounding, but is not required. Other interpretations are also welcomed! Example (more like the second set of takes)
