"What? You want to ask me some questions? Ah well...."
Gender: "First off, I'm not even going to answer this one."
Age: "I'm nineteen.... Mom, just because you're immortal and don't need to keep track of your age doesn't mean you can neglect me the same way."
Height: "Ah... I don't really know, actually.... Well, I think I'm about an inch taller than Dad now, and he's around six feet, right?"
Weight: "Mom, our scales are made for small objects, such as coins. I seriously doubt I'll be able to fit on one."
Hair: "It's obviously black...."
Eyes: "They are black too, actually, perhaps a dark green? I suppose it depends on my mood."
Additional:
Keres looks like your average Lunar citizen. In a kingdom of everlasting night, it's normal for one to be as unnaturally white as he is (it looks like someone melted a bunch of paper and stuck it on him). He, like his subjects, looks almost sickly. For Keres (I don't know about the citizens), he is not unhealthy in any human respects, actually being physically stronger and fitter than most (well duh, he is a hybrid of a race created to be that way). However, Keres does not eat. Not the way he's supposed to, anyways. You see, the prince of Lune does not drink blood. That's about as nasty as a prospect to him as it would be to us.
Despite all of this, Keres posesses a noble sort of face and appearance. Just by looking at him, you can tell he obviously isn't a normal person. Also, he does NOT like touching people, at all. Even his parents.
Personality:
Vampires are known for their dark, brooding nature, and werewolves are a likewise infamous for their spitfire tempers and passionate personalities. Werepires also have common characteristics and mannerisms. But being a hybrid race, the amounts of qualities one could receive from the parent races generally varies from person to person.
Keres is, to the passerby, a quiet and stoic young man with not much about his that's very noteworthy. He is, in fact, a wallflower, and is easily ignored by the general public. While he is stonefaced, Keres is an extremely capable actor, and has a 'princely', talkative, persona he wears when the occasion calls for it. Even then, however, his smile will not reach his eyes.
Keres is reserved person, for underneath all of that rocky exterior is a fiery core with a short-fused temper. Even if he doesn't show it, Keres is easily annoyed and makes very rash and nearsighted decisions. However, he is very loyal and will follow through with his choices, however stupid they may be.
Thanks to his hard-to-approach aura, Keres is unused to people and doesn't know how to interact with others outside of public socializing. Especially if they are young, for he grew up in an all-adult environment. Even if Keres wanted to befriend someone, he wouldn't know how to go about it.
This prince is the type of person, where if he truly smiled, the whole room would light up as a result. Despite his pokerface, Keres can express an amazingly deep level of emotions, which is actually a dependable werepire trait. They are famous for the intenseness of their feelings and relationships, if you asked a random person about them that's the first fact that comes out of their mouths after 'vampire-werewolf hybrid'. It's thanks to this intenseness that werepires are extremely cautious about befriending or falling in love with others. If they dare make a bond, and that bond somehow backfires or ends up badly, it will rip them apart from the inside out for the rest of the werepire's very very long life.
History:
Keres, the sole prince of Lune, was born on the rare occasion of a sunrise. You see, this is an extremely uncommon event in Lune, and it was taken by the general public as a bad omen. And for once, the general public's paranoid opinion was correct. Thanks to the circumstances of his birth, Keres turned out to be... unusual. While his canines were rather sharp (though, admittedly, their were human children with sharper), Kere's would not drink blood, could not transform into a wolf, and most of all, aged. Normal werepire children simply grew very very quickly. Keres, on the other hand, aged like a human, albeit much much slower. It was thanks to this, that Keres was regarded as a failure, a cripple. While his parents were very loving, he grew up in an all-adult environment, and was kept away from others his age. For, besides the witches and the more human-like creatures, there was no one else like him.
It was thanks to this slow-aging process that his family forgot, over time, that Keres actually grew. When he hit relative maturity, not only did they still treat him like a child, but they had left him on his own (deeming him hopeless) for so long, no one was close enough to him to realize that, on his own, Keres had, in fact, grown into his powers.
But his parents and their advisors didn't know, or acknowledge that. They had long ago made plans to engage the prince to a strong female who could rule in his stead (after all, if Keres was so weak he obviously wouldn't be capable of making healthy decisions on his own). Now that they had found one (a vampric duchess), it was time to tell Keres he had a fiance.
