Tagan, the Emerald Claw are a knightly order in Karrnath, who are extremely well known.  They are disavowed by the king, and are at least slightly insane.  They have been spotted throughout Khorvaire doing seemingly random acts of violence.  Some now theorize that the Emerald Claw is simply a convenient disguise that thugs throughout Khorvaire adopt.<br/><br/>The Emerald Claw has a small army of fanatical but incompetent soldiers.  They're basically faceless stormtroopers, the generic terrorists of Eberron.<br/><br/>Your character will know about the existance of the Emerald claw, and know that you just have to put an Emerald claw on your shield and maybe travel with some undead.  Not that realism would be too important to acceptably fool Riedra.
