A relic once left to be damaged by the passing ages of time was rediscovered and repaired back to how it was once. The relic was then upgraded to the Zenith. It was then infused with souls of fallen foes and became the atma which then became Animus.
The Animus then went on to become the Novus after being merged with materia to make it grow more powerful. It then became the Nexus after it spirit bonded with myself and then … it was reforged into the legendary arm – The Nirvana!
And now its true power has been unreleased and although the future of it is not known – I now have the Nirvana Zeta!
