Kelbor was born on Mandalore to House Krakos, a clan of House Vizla. He
joined Death Watch at a young age and was a member up until the death of Pre Vizla. Kelbor had became disilussioned with Death Watch, he believed in the cause but not their methods.
His parents were renouned Mandalorian warriors killed by Maul's forces.
Kelbor suffers from trauma from the killings he did in the name of Death Watch, mainly the bombing of civilians in the name of Death Watch.
After Maul's conquest of Mandalore Kelbor snuck off-world and renounced his Mandalorian weapons and armour, believing he was not worthy of them because of what he had done.
During the years following he worked as a mercenary and bounty hunter and developed a drug addiction to deal with with his trauma and shame, wishing to forget what he had done and the loss he and endured.

Addiction (10) - Kelbor is a death stick addict, he uses the drug as a crutch to cope with his trauma from his time in Death Watch.

Debt (10) - Kelbor's addiction to death sticks now means he owes a large debt to a local Black sun crime boss after repeatedly being unable to pay for the addiction. He is now in the pocket of this crime boss if he wants to get his next hit.
