Howl

When his elder siblings were killed in an attack, Howl was trained by Rapidwing to use a sword. He soon discovered that his father had been learning to use Shade magic, which he refused to teach him in fear that he would use it for evil. Howl attempted to blackmail him into teaching him, but failed and was banished from the clan.

On the outskirts of the Scarred Wasteland, he taught himself the cruelest forms of magic, as well as using the physical skills his parents taught him to survive and become one of Fenrir's trusted allies. He intends to kill Fenrir and lead the clan himself- the first step in his longterm plan of gaining ultimate power.

He might seem intimidating, but he is just a brat with a sword.
