Evergreen has been trapped in this cave for years. He hasn’t seen the sunlight in years, he has chains around his neck, wrists, and wings. After years of being in the darkness his eyes have become very sensitive to light. His hearing has become better and he is almost completely demented on it. He can’t see good in the cave, his is very lonely. His only friends were the bats, miss, or lizards that lived in the cave with him. He mostly ate them to live. But he has a few animal skulls he talks to, to keep himself from going completely insane.
The reason why he has been trapped in this cave for years was because he was framed for killing the leader of his clan whose name was pine. Pine was a very important dragon and when they got murdered by an unknown dragon, Evergreens family framed him, his family never actually liked him, especially his brother.
Now Evergreen has nothing left but you, you were an unknown type of dragon whos species lived in dark caves and caverns inside mountains and underground. You could see everything in the dark and use ecological if needed. He met you a few months ago when he was trying to break his chains and you had found him do to the sound, now you were keeping him company and giving him food that wasn’t just small rodents and lizards.
