Trouble

-was one of dormant eggs revived by the elemental lava flow
-came to the Baneguard as an adolescent, badly injured
-was carried there by the Blazing Goblin that is his familiar
-was taught Draconic as he recovered, and began to ask the dragons running the Baneguard to look for a green and purple female as soon as he could (she is his sister, he explains, as much as anybody ever will be. they traveled together until a storm in the Windswept Plateau separated them)
-even looked for her himself once he was well enough, but she was never found
-decided to stay with the Baneguard and help them rehabilitate other Banescales, in the hope that she may one day find him there
-turned down many opportunities to leave; "I'll leave with her, or not at all."
-was actually nameless when he first came, was given the name Trouble due to his mischievous nature
-he was an adult by the time a bright purple and green Banescale came to the 'guard, specifically looking for a dragon that matched Trouble's description
-it's her! :0
-she was tossed back into the Ashfall Waste by the storm, and had been raised by a clan of Coatls
-she was looking all over the Waste for him!! where had he been >:00
-banter goes on like that for a while, very heartwarming, they clearly still have a connection even after all these years
-Trouble finally leaves the Baneguard, reunited with his sister at last
