- "A thousand years of war between us will not be forgotten!"
- ―Ronan the Accuser
Outraged by the peace agreement, a Kree named Ronan the Accuser began exterminating Xandarians throughout the galaxy. Nova-Prime Irani Rael called a Kree Ambassador asking for a testimonial from the Kree Empire condemning Ronan's murderous actions but the Ambassador ignored her.
Ronan made a pact with Thanos to retrieve the Orb in exchange for destroying Xandar. After Ronan achieved the Orb and discovered it was one of the Infinity Stones, he betrayed Thanos and kept the Orb for himself. Ronan attacked Xandar with his ship, the Dark Aster, and a thousand Necrocrafts. With the aid of the Guardians of the Galaxy and the Ravagers, the Nova Corps managed to win the battle and retrieve the Orb.
