Agate

As a hatchling, her sole desire was to be a warrior like her mother. She studied sword fighting and became quite skilled at it, even more so than her mother. She held a blend of quiet dignity and respectfulness and enduring fearlessness and charisma which made her popular among both her elders and her fellows. She was reckless, though, and it was her downfall.

This happy reality changed when she she became the victim of a terrible injury that infected, leaving her sick, weak and constantly tired so she couldn't even pick up a sword. She was devestated and her temperament violently became foul. She moved to a hut made for her away from the village and lived as an outcastby her own terms. Others quickly learned to stay away from her, for her tongue became even more sharp and ruthless than that of her mother. There was only two dragons that refused to leave her in her brooding loneliness: her dear cousin, Jasper, and his mate Dahlia. Dahlia gently tended to Agate despite her protests

Now she teaches the art to all those who listen, especially travelers who need some form of defense whilst traveling through the Shrieking Wilds or any other dangerous place. She has discovered that she isn't much of a warrior, though, and hates the idea of killing another dragon or blood, for that matter. She loves dueling though and always is seeking a worthy competitor.

She is impatient as a teacher if her students seem distracted or not into it and her words can crush anyone who isn’t fully internally motivated. For those who press on, give it their all and earn her respect, however, she can be much more encouraging and genuinely root for them to succeed.
