Monster Name: Wurm
Young dragons begin their life cycle as wurms, though most never develop beyond that stage. Wurms are clever and sly, if not especially intelligent. To develop into a drake (and eventually a dragon), a wurm must have ample space and resources. They will not develop if they live near existing drakes and dragons. They must seek out a habitat that has not already been claimed by a larger counterpart.
Since the chances of further development are low, most wurms will band together in covens for survival. They are bold and highly aggressive creatures, if not particularly intelligent - the intense competition for food and territory demands this.
