Tanzanite

Tanzanite was born cursed. Or so that's what he says. His siblings were all born healthy and happy. They were strong and durable, shaped by the twisted and diseased lands of the Plaque dragons. And while his siblings were shaped by the harsh lands they called home, it was like Tanzanite was infected by the lands. Such a small thing he was. So weak. So tired. In a world of survival of the fittest, he was not the fittest.
He was a lost cause they figured. He wouldn't make it to his adult years. They underestimated the fight he had in him. He tried each day to prove himself to show he wasn't a lost cause, that there was hope. But those attempts were largely ignored. Desperate attempts of a fading dragon they called it. Such a stubborn thing he is though, so he kept trying only stopping when his body could no longer take it.
One day, he laid by next to a small pile of wretched fish panting and wheezing. He was tired but most importantly he was frustrated. He had caught a measly amount of fish for the flight and yet he was beyond exhausted, like he had just finished battle. He wanted to scream. He wanted to cry. Why did he have to be like this? So weak? So useless? As he laid there, a young Guardian wondered over to him. He hissed weakly for her to leave him be but she instead smiled and flopped down next to him. "I found you my charge" she said excitedly before nudging him. "I'm Minoka, what of you?"
From that day on the Guardian followed him around, diligently watching out for him and assisting him in his work. Of course he was not accepting at first, hissing and snarling at her. Tried to chase her away...but she never let. Overtime he came to accept her presence. And soon he started calling her friend.

He won't ever admit say it out loud but he is truly thankful Minoka found him that day. He is thankful to have such a good friend.
