Most loyal creature to Baroness and arguable extension of her own will. Has never failed to retrieve a target for it’s queen. Flying horror – almost entirely invisible – it’s plumes reflect any light around them into the night. Some believe it is a creature composed of hundreds of other birds… leaving anyone in pursuit that much more paranoid. It ebbs and slows its prey psychologically as a result of this very nature. Only when not in flight is it possible to see: a huge writhing tangle of demonic pitch black feathers. Within them things sift about impossibly – massive talons jutting forth before succumbing to dozens of giant gnashing bloody beaks. The true nature of this creature is similar to murmuration magic of the cloaks. This is impure, however, and has lightblood at work in it’s creation (it drips this wherever it lands – each flight consumes large amounts [imagine the portal as an open wound]. Most of this blood is indeed Ada’s…) It is a living portal to somewhere. This somewhere is the resting place of the dead god of ravens slain during the upheaval. It cannot be slain so much as the portal can be closed. Because Hallowed blood cancels lightblood – only the risen or those wielding potent enough condemnations could defeat it. It is legendary because it has been invincible until now. All fear it. It has served as an excellent negotiation tool for the baroness. Use shambling mound or something.
