B'Eryn, commander of the Bird-of-Prey Nok'Lar, claimed to represent a growing faction of Klingons dissatisfied with their alliance with the Cardassians. Stephen April met with her on Organia under a flag of truce, at the behest of Sunni Moon. B'Eryn was described physically as foul and smelly, like most mirror Klingons, with deep, brooding fiery eyes, sharp, jagged yellow teeth, a swarthy complexion and an earthy stench, as though she had worn musk cologne. Alexis Crimson later learned that B'Eryn was the contact of one Captain Xelix, a Betazoid in collusion with the Alliance.
