The Falcon's Claw was originally part of the Right Wing of Horus. However, due to Mir's Rebellion and the subsequent Virus War, one of the two Plasma Bells that kept the Wings of Horus airborne was destroyed, which caused the collapse of the Right Wing. A few small pieces of that Wing broke off during the collapse and got caught in the gravity field of the Plasma Bell that remained, thus forming the ring of small islands around the Left Wing of Horus, and the Falcon's Claw itself.
