Name: Kassandra

Age (18+ please): 153, considered a young adult for a dragon

Gender: Female

Race: Water Dragon Shifter/Human

Appearance: Kassandra is chubby with dark skin and seafoam white hair. She has strange, forked ears that mark her as inhuman, but they don’t look elven and she’s too tall to be a dwarf. Despite having a sweet smile, she has a carnivore’s teeth. She usually dresses a bit outside of fashion as she can’t quite keep up with trends over the many years. Her dragon form is a pastel blue and white.
Personality: Kassandra is gentle and caring, and looks like she couldn’t hurt a fly. In truth, she could do so easily, but only if the fly was hurting others. While she has few friends, she tends to take good care of the people under her watch. Beware her if you ever get her angry. 

Strengths: swimming, cooking, staff combat, water magic, singing

Weaknesses: Hot days, bad food, weapons with anti-dragon properties, deserts, easily dehydrated, tainted water is worse for her

Brief Bio: Kassandra has served as the local fishing village’s guardian for over 75 years, and has earned the trust of the humans there. She helps with large catches, rescues people in storms, tosses brigands out of town, and sometimes teaches the children when their parents are off on sea voyages. She has not left the town in some time, because she is comfortable there. Unfortunately, life isn’t all comfort. Being chosen will test everything she knows, and is.
Other:

Is this any better? I added the weakness of dehydration.
