History
It is unknown what year Lucas was born but it is presumed to be around the earyl-mid 2360's after the ISA victory in the Second Extrasolar War. In the year 2367 Lucas and his father Michael were forced out of their home in eastern Vekta after the Helghast refugees were given the entire eastern half of Vekta as their new home. State of New Helghan was established around that year and the newly created nation had forced all of the local Vektan population out of their territory and the Kellen family was no acception. Lucas and his father soon began to leave and managed to sneak past Helghast security drones and gunships that had began to tear the city apart. Soon the Kellens ran into Tomas Sinclair, a Shadow Marshal and he began to escort them but just as they were near the wall, a drone spotted him and Michael was soon shot and executed by 3 Helghast security troopers despite the fact that the two were leaving for west Vekta. SInclair soon took lUcas under his wing after saving him from the 3 Helghasts. AT the age of 13 years old Lucas became the youngest cadet accepted into the Shadow Marshall Academy and was at the top 5 of his class as the years went on. Eventually he was captured and was traded off and soon met Echo.
