The Oathbound are the leaders of Erdas's guards. They wear black uniforms, brass vambraces, and brass collars. They are sworn to protect all of Erdas's leaders and defy The Greencloaks.

In Stormspeaker, it is revealed that Anka founded the organization.

Oathbound names appear to be the opposite of what the person is actually like. Brunhild the Merry is very grouchy, Kana the Honest was a spy, Wikam the Just is very unjust.
