Physical description:

It appears as though Solaria's body is just a ball of light that glows as brightly as a torch that is roughly the size of a human head. The glow impossible to see through with a naked eye. The entire creature is made out of super-dense plasma that it's like a thick liquid that swirls around with different colours, though one with good vision can faintly make out a thin crystalline structure inside that looks almost like a spider web, linking countless little nodes together.

Over all the main colour of Solaria is white, but there are sections that have a good amount of violet and blue, as well as a tiny bit of green and yellow. It seems that the colour configuration seems to change like some form of facial expression, as the over-all glow and intensity of the colours
seem to change in sync with Solaria's mood.

Typically, over Solaria's entire body it wears a crystal shell made out of some unknown crystal material. It appears to be something similar to glass or quartz which is a mostly clear material that's very hard and slightly iridescent. The entire shell made up out of tiny rhombus diamonds each about the size of a person's thumb. All of the crystal pieces fit together to form an egg-like shape that is fully enclosed around the wisp inside, yet despite this unusual form of armour, the wisp can still freely fly around completely unhindered by it.

Should you try to touch the wisp, you would feel an invisible repulsive force give more and more resistance the closer you reach towards the wisp; giving a similar sensation to pushing two same-pole magnets towards each other. Along with an increasing sensation of static electricity that tingles your skin and slowly starts to make your body feel numb.

Solaria appears to be able to have perfect flight in the air and makes no sound, able to hover perfectly still, but seems to prefer to wander or orbit around people it's interacting with. Though the quality of flight seems to differ depending on where you are. Such as if outside in an open field you would hear a soft sound of air and the wisp would tend to bob in the air or drift around.

Personality:

The most immediately noticeable trait of Solaria's personality is that it appears to be friendly and rather casual. Seeming to enjoy being silly and at times hyper, but seems to have a lot of self-control when dealing with serious matters. For such an unusual creature it behaves rather human, sort of like what someone would expect a fairy to behave like. Though Solaria also shows a lot of dedication to logic and science.

One feature of Solaria's personality is overall it seems to give the impression Solaria is female just from the general behaviour and it's voice sounds feminine, similar to a youth aged girl, though overall there's serious doubt if it actually has a real gender.

Simple abilities:
(Please note that many of these abilities a typical character may not be able to detect)

Infrared, Ultraviolet, full-colour, and true 360 degree vision
Repulsion levitation (flight by pushing away from things)
Sound mimicry
Able to create crystal from basic materials


Abilities that require explanation:

Light-based manipulators - Solaria can manipulate the EM field which includes light. She can focus light into a beam, suck light into itself, darken or brighten ambient light, and create vivid light-based illusions and images.

Kinetic tendrils - Solaria has thousands of tiny tendrils made out of near-matter energy that can pull on objects. These are invisible to the naked eye and typically go unfelt. They can however be seen by equipment designed to be sensitive to ionic radiation or electromagnetic cameras. If seen they appear like super thin hairs that extend as far as 7 meters that skitter across surfaces similar to a plasma globe. It appears that this is where Solaria's true flight comes from. It's body is typically suspended in the air by hanging off of countless objects in the room, distributing it's weight across everything to make it seem and feel weightless.

Radio sensing/emitting - Solaria unless stated otherwise is always transmitting broad-band radio waves that randomize on different frequencies. To most this is just noise that equipment could pick up, but those advanced in cryptography may notice it appears to actually be a language of some sort in an unseen network. Characters or equipment sensitive to radio will hear clicks, pops, and random digital squeals on occasion which may sometimes disrupt wireless devices (cell phones, wifi) unless Solaria acknowledges them and avoids using those frequencies.
