Arjuna can come back from existence erasure

The final aspect of biology you needed to impress upon your soul, and surprisingly the hardest. It's as if...hmm. You had to actually work up a solution of 'cracking open' your History and connecting it with your Origin somewhat to create an entirely new fundamental aspect of your soul, which you labeled Structure. It was rather difficult, but the end result was everything you hoped for. (So long as the very idea of Optimization exists, you can eventually re-corporate yourself back at low power even if you'd been erased from existence! Current time until re-establishment of existence: 100,000 years. After re-establishment, a further 100 years is required to return to full power. Can now permanently host 1 Biological Trait within your soul! Traits hosted in the soul cannot be improved or evolved from, but remain present even when your body is destroyed or inoperable.)
