Acacia

Acacia, in her centuries of service to the Arcanist, began to change. She would spend weeks- sometimes months- alone in her studies, sending secretive correspondence away from the clan. Her body began to change, as well; her wings slowly begun to fade, turning ragged and dull. Her scales lost color in odd shapes and patterns, almost as if ice had coated her body.
She also acted colder- when not studying alone, she would rarely interact with any in the clan besides her mate. Acacia's words were hushed, low, and unclear; every word was mumbled and her sentences slowly grew incomprehensible. No one is sure as to why the change, but rumor has it her meticulous studies involved some.. odd substances, that may have altered her mind.

Not used to being around other dragons, this little lady is pretty stubborn. But she has a fiery spirit and naturally takes charge of any situation! She tends to rush into things headlong, which gets her into some prickly situations from time to time. Luckily she has others in her clan to save her hide. Though she doesn't like admitting it, she loves being around them.
