Lord Sicarum, born Natis Ambrun, was a Human male from the ecumenopolis Alsakan. He came from a rich family, which he abhorred. Natis ran away when he was young, only to crash-land on Korriban. He was found by the Sith of the New Sith Order and was accepted into their ranks. Natis changed his name to Sicarum and trained with the Sith until they revealed themselves to the galaxy in 127 ABY. He fought with his brethren during the Sith-Imperial War and helped them hunt down Jedi fugitives.
