Guide to all the wolves in the packs

Angustus is a small, scrawny wolf, his name meaning 'too small.' As his pack leaves their old home in the forest, to travel to the mountains, Angustus finds that he cannot keep up with the rest of his pack, unlike his sister, Willow. As days go on, Angustus becomes more and more tired, lagging further behind his pack. Finally, the alpha, Blizzard, decides that Angustus is slowing down his pack and is a liability to them. He banishes Angustus, leaving him alone and starving on the outskirts of a snowy mountain. With nowhere to go and no way to survive in the harsh environment for a pup like Angustus, how will he cope?
