Ankoku's past is unknown to anywolf. Some suspected him of dark connections. Ever since he was found as a small yet-to-be weaned pup, he has never made a single sound. This worried the nursing wolf and the herbalist tending to him before realizing he is mute.
While this information remains unknown to his pack, he is a shadow being, born in a Shadow Realm. A realm feared by all beings gives him the void magical capabilities. The Shadow Realm is connected to him through magic and teaches him all he needs to know. His rank within the Shadow Realm remains unknown.
He is mute but can communicate in other ways, such as Wolf Sign Language. He has perfect eye sight and can see quite well for a wolf. No shadows can hide from him. He has already mastered shadow spells and void spells. He is usually quiet and focused pup. But he is very impulsive. He sometimes acted on his paws rather than waiting. But he is patient enough to listen.
