Personality: Smart, as I already said. She's also shy at times, and has no friends except the robot she made when she was young, Xara. But she is extremely curious, and that leads her to trouble a lot of the time.
Appearance: Light blue skin, black eyes, bright purple hair pulled into pigtails. Wears a standard uniform for a female in her race, but her left hand is mechanical.
Background: When she was young, her parents were killed by her planet's leaders, as they thought her parents were plotting to kill them. Fortunately, Jast had just been born a few days prior, so she was spared, unlike her brother and sister. Jast was placed in something similar to what we call foster care. She decided at a young age that she wanted to be an engineer. And that's exactly what she did. She began making things, and progressed up to robots. That was when she made Xara, programming her with not only AI, but some of her own memories, and common sense that most robots lacked. She grew attached to her, and Xara never left her side. As Jast got older, she fell in love with one of their planet's strongest soldiers. Unfortunately, he died a few years later, leaving Jast heartbroken. She then dedicated all her time to her work, not letting her mind wander back to her love. She then heard about a new planet that was discovered. Jast was the first to volunteer to go check it out, but, as she was only an engineer, she had to prove she would be able to handle it. And she did.

Also, something you should know about her race, in case you want to make a character of this species.

Their skin color is determined on where they're born. There is three. Blue: water. Purple: flowers. Green: grass.

Most of them are green.
