|Behind the Scenes|
Like all Wesen, these creatures can shift between a human form and a monstrous form. In the latter, they have sharp teeth and gills.
They have been described as a vicious species, with a tendency for going into bloodthirsty frenzies and losing all sight of reason.
Culture and society
In their human form, they tend to be revered as great warriors and protectors of their tribes, but need to honor the vow not to consume the flesh of other creatures. Those who break this vow will be banished and become outcasts.
