Beginning

One day, a mind jumper named Snow Flash, who lived in a small town in Siberia, saw something bright fall from the sky into the forest at night. It turned out to be a wounded Star being, a space traveler. Flash tried to help him, she took care of him for several days, but her efforts were in vain - his wounds were too serious, and the Star was already on the verge of death. But he asked Flash for a request that she take care of his heart - his life source, that is able to reborn into new Star being. When his body crumbled into stardust and Flash took the bright heart, her mental energy that came into contact with the star changed, became something new. So Polaris was born.

Getting a job

Polaris grew up as the daughter of Snow Flash, from whom she learned everything a mind jumper should know (even if she wasn't completely one), including everything about diving into other's minds. Polaris decided to use her ability for good and began to help people in the town cope with mental problems. On one of her working days, a visitor came to her from outside the town who, seeing her in action, offered her a place in an international organization as a psychologist. Polaris agreed, deciding that helping those who protect the world, she would do more good.
So she got into the IBP, where she still works

Trivia

• Her father's heart is her life source. It's a bright star in her chest, that pulses and fills her with energy. It can't be pulled out, but can be cracked or even shattered. If it's cracked, Polaris will feel sick, but cracks will heal itself after a while (depends on the severity of the crack, from couple days to several months). If it's shattered Polaris will die
• Unlike mind jumpers, she has normal organs too and can consume both mental energy and normal food. Her digestive system is similar to that of Star beings that feed on pieces of meteorites, space debris and other not the most edible things; because of that their stomachs are incredibly powerful and assimilate organic matter without a trace (and so they don't have intestine). Also, since Pal doesn't have lungs, her stomach is placed in her chest. Her midriff is her energy deposit and almost completely filled with her astral part - liquefied mental energy. Also that's usually where Ursa is "located" (here or her head astral parts)
• Ursa actually can leave her body, but probably never would, since it will makes both of them really weak and vulnerable
• Polaris can also work "in the field" when she helps an agent cope with stress while working (especially useful for young and inexperienced workers). To do this, she goes with this agent in their head, as a temporary second mind
• She doesn't have a nose or lungs and she breathes through astral parts, and that's why she prefers to keep it as much open as possible (tho having belly open is optional, it's just feels more comfortable for her). She unfolds her head frills when doing her equivalent of yawning
• She, even tho is a half mindjumper, doesn't need shell (skin-like "suit" every MJ has) since she has an organic body, but her mother made her small piece of shell that Polaris keeps as a lucky charm! She can even control it's form and color and she always keeps it on her body (because it will disintegrate very quickly without her astral part nearby). In her casual form she either wears it under the clothes, as wristband, or as the "hair tie" she uses to fasten her frill
• Polaris has four triangle marks on her body - on forehead, hands and back. It's her "points of connection" with Ursa. When they're not active (when Polaris is not actively using abilities) it's looks more like a markings (especially on forehead), but if Ursa starts to change her form (like creation of big wings), triangles become solid black (often with white outline) and floats inches from body. They're hard to damage, but if they are, connection between Polaris and Ursa will start to "mess up". They can regenerate even if completely destroyed, but it takes a while
• When Polaris is in someone else's mind, she and Ursa have a bit more variability of shapeshifting, including creation of simple objects (like machete she uses in fight form)
