A million kinds of beasts live on the continent of Genertela in Glorantha. They appear in all the stories of the world. Some are friends, many are foes, a few are magical harbingers, and others are just food. Horses, dogs, and cats are nearly ubiquitous, wolf backs and metal goats are foes, ravens and rattlesnakes can talk, and cattle and deer are the feats of every story.
