Marketeer
Marketeer is the nickname given to him by his father's Junker friends. His father was a respected and noted Junker himself before his death.
He was given the name because even at an early age Marketeer could always find what you were looking for and sold it for a reasonable price. That was the legacy that his father gave him who enjoyed great respect in the Junker circles and Beyond.
Before his father died the Junkers were a peaceful Group and conducted business in a fair manner with all factions.
Then came the Great break-up and the disruptions thereafter. It was during the traumatic upheaval that the Junkers became a crude and somewhat violent organization.
After this turn of events Marketeer left the Junkers and found that the RRJDS Guild was as close as he had found to that of his previous happy years and a place that he could call "Home" again.
To honor his father, Marketeer officially adopted his nickname and never used his real name after that.
