Aster

A prisoner from near the center of the Milky Way, the only one left of her own race. Oftentimes has a straight expression on, which unnerves people looking at her.

In reality, she's soft spoken, well mannered, and quite sweet, though it's hard for her to express it as she still struggles to show herself to others. Charon named her Aster, a play on the designated name she was given by his kind, A*, after the black hole in the center of their galaxy.
