Nettle

Nettle is a half Vargr who was outcasted by his tribe at an early age. He's sickly and weak, but determined to move on regardless. He and Grey travel and work together as Nettle seeks to learn the art of healing. 

Nettle is very pleasant, kind, and good natured. He does get slightly annoyed when people mistake him for a child, but overall is very patient and caring. He believes that nobody is truly bad, and in forgiving and trusting. He is aware that he's naive, but keeps this view regardless.

Nettle is bothered by his weakness and hates that he constantly has to be protected and coddled. Post timeskip he finally puts his foot down and lives to his fullest, fighting alongside the blue lions. He finally has confidence in himself and his abilities, and is encouraged by his allies.

In his last breaths he begs his allies to not let his or anyone else's sacrifice be in vain, and to pursue their own happiness no matter what others say they can do. His last words are an "I love you" to Grey, his brother by bond
