Markus Keller was born on Planet Denver to parents, who were more interested in following the latest fad than having a child, but the trend was to have a baby, and the Kellers were always trendy. When Markus got older, his parents took less and less of a role in his upbringing, seeing that he had already passed on being fashionable. This gave Markus a less-than-wholesome upbringing, and caused him to get into any little scuffs as he grew up with the elites on an elitist planet.
At the age of 25, flush with cash from his recently matured trust fund set up by his “loving” parents, Markus bought himself a Collector from the Junkers on Rochester. Markus had been living amongst the Junkers for several years, doing the odd job while biding most of his time at the bars. This tended to cause problems for Markus, as his take-no-crap attitude and quick temper got him into many fights.
One such encounter involving the sister of a particularly nasty Liberty Rogue saw to it that Markus needed to get lost out of Liberty space in a hurry. Luckily, he'd heard of a job with Cryer Pharmaceuticals, who had need of pilots willing to make the dangerous journey to their newest facility in Sigma 17. Markus jumped at the chance and was soon doing regular runs that other Cryer pilots called suicide.
