Abe Yuristoli is an immigrant from the recently dissolved nation of Trekistan. After his home collection was destroyed by renegade Geyper Men, Yuristoli applied for travel documents to visit distant relations in the new world, but due to a computer error his flight was diverted into deep space. Technically, without an authentic Deep Space Visa (DSV), Yuristoli is unable to return to the Earth.

Finding himself in an unusual black hole between legal authorities, Abraham was stranded at moonbase Gecko 7 for almost a year before signing on as a T19 Runner.

Abe doesn't speak the language very well.
