 Nova Cat Abjuration
In April 27th, 3060, Grand Council of the Clans voted to Abjuration or eject Clan Nova Cat from Clan space, with only month warning. Clan Jade Falcon's 53rd Battle Cluster attacked the Nova Cat's garrison forces without Trial. The Falcons had felt that the cats were dezgra, did not deserve honor of a trial. Nova Cat defenders instead of conducting a fighting withdraw, went head on against 53rd's forces to prevent Falcons penetrating into Nova Cat's major population centers. These Nova Cats attempted to buy time for their civilian castes to evacuate the planet, and paid with their lives. The 53rd Battle Cluster destroyed all Nova Cat forces to last warrior, prevent majority of the civilian caste from escaping the planet.
