These birds are intelligent and trainable enough that each Altonian soldier has a small flock that follows them into battle. They are used in war, racing, as a source of eggs and feathers, and for messengers. The arrows of Altonbrun are often brightly colored, using kroke plumage.
A kroke can weigh as much as 2,000 lbs, and stand as high as 15 feet tall. Their wingspan is generally a modest 12 feet, but they can leap great distances.
Although they have large beaks, their bite is instinctually reserved as a defensive measure against Welkenlord Eagles. Instead, they rely on their powerful legs and large talons (which their riders augment with steel spurs). This is enough
