Darth Kraven was a Sith Knight during the Successors War and by 128 ABY, a former faction holder in the conflict. Although not particularly fond of either Darth Proditor or Darth Sucasa, Kraven believed he stood a better chance of surviving the conflict in a strong position by usurping Proditor's power from within.
Kraven later took part in the attack on the conclave on the Sluis Van Shipyards.
