Mara [Corrupted! Aquamarine]

Mara is Kaelah's seeing-eye aquamarine. She corrupted naturally rather than through diamond influence. Mara and Kaelah, before Mara corrupted, were in a serious relationship, but then Mara corrupted and Kaelah couldn't bear to have her beloved Mara shattered, so she adopted Mara as a seeing-eye aquamarine. 

Mara both looks and acts like a housecat. She also happens to be extremely loyal to Kaelah and rather snooty.
