SoulFlayer was born on the planet Ungor in the outer rims uncharted regions. according to the knows records of the old Republic a colony ship crashed there eons ago and from that on nothing is known of the fate of the people.
on Ungor it is a custom that children get their names when they reach adulthood and have proven their worth in  a battle. he got his name thanks to his height and rock hard determination.
at the age of 21 he left Ungor to see the rest of the galaxy and went directly out into a galaxy of turmoil where Rebels and imperials fought all over the sector. SoulFlayer thought their battle interesting and decided after 5 years of idle exploration through the galaxy to join the imperial cause because partly he agreed in their mentality and he saw it as a the best chance there was to test his mettle against others on the field of battle.
