Plato's parents immigrated to Mies VII when he was young.
When he became a capsuleer he learned to fly industrials, and traded goods around Gallente space.
After a few weeks of trading he was recruited by some old friends to join them in Wormhole space where he spent several months learning the ins and outs of wormhole life. Eventually, his corp-mates decided that they had made enough profit from their wormhole venture, and executed an orderly withdrawal.
Since then, he has returned to high-sec, and has grown his assets through further trading.

After years of peacful existance Plato joined the Edencom Defense Iniative to fend off the Triglavian's invasion.

The invasions brought him in contact with pilots from many groups throughout new eden that he'd never had contact with.

He found that the pilots and leadership of the Sister's of Eve Roughriders were a good fit for his desires and philosophy and joined up.
