Aetas: (Aetas means lifetime/age in latin, not ripping anyone off here.)
The Aetas are a very sought after race. Why? Because of their powers. You know those old fairy tales, the ones of earth? Where you have your fairy's, your leprechauns, all of your 'little elf like people,' that help out for prices or play tricks and don't? Well, that all stems from the Aetas Race. Where Earth, and other races got the knowledge of them, not many really know, it's speculated that a few let themselves be seen, so as to play a few tricks on the unsuspecting public.
But, that would only be a few jokers, as the Aetas rather like to keep to themselves unless called. Because as I was saying, their powers are sought after. They are, to put it in simple terms. Wish Granters. No! Don't think for a minute, just because they grant wishes you can now go outside your home and shout "I WISH TO OWN JAPAE!" It's not going to happen. Or, "I WISH TO OWN THE DIMENSIONAL PLANE AND BE THE MOST RICHEST, STRONGEST, MOST POWERFUL AND OMNIPOTENT BEING IN EXISTENCE." ....Keep dreaming. Even if the Aetas had that power, it's against their own personal beliefs to do such a thing, as its a form of interference.
No, the Aetas are not THAT TYPE of wish granter. They grant smaller wishes. Things on a small scale, but even then, the wishes are never how the wisher perceives. Not that the Aetas make them evil, or get them wrong on purpose, it's just the way their powers work. Say you wish for sword? You never specified what kind, and may get a sword larger than you are, or so small you can't even see it. Which takes us to how you wish.
You must always specify, and be damn detailed. Any slip of the tongue, or wrong meaning in your wish, and you won't get another chance unless you have reason to have.
Aetas grants wishes as they see fit, if you come across one, or if they see it as a wish they want to grant. Some wishes require payment, some don't. It depends on that particular Aetas and if he or she is busy at the time, or if they like you. They can also make the wishes go wrong on purpose if you manage to annoy such a being. After all, they aren't your bitch or slave to force wishes and every desire of your heart out of. They are a sentient race that uses their powers as they see fit.
Ah right, desire, that's another thing. Your wish also stems from your desire. If you wish to have an apple when really you're craving a peach. Guess what? You'll either get a peach or some cross of the both of them. Aetas grant wishes, but desire drives them.
A typical Aetas stands about 2 ft tall, they are pale skinned, and usually are known to have ambient colored eyes. Their hair ranges from any odd color, and never natural colors. And upon their back they have a very chibi-like angel wings, like that of (anime chibi angel/clamp). The Aetas have a variety of personalities, and no Aetas is alike. If they take a liking to you, they may follow you around and grant your every wish as they see fit! Or, you may end up pissing one off with demands (*cough*Hawkeye*cough*) and you'll get one following you, cursing your every desire to something bad.
It really depends.
