Yansan was a Ho'Din saboteur. An ecology student in his native Moltok, Yansan always despised technology to a fanatic extent—even for a Ho'Din. He concluded that the evils of technology were too big and that he should "free" the galaxy from technology. He enlisted in Traval-Parcor System Institute of Technology, to learn all he could about the hated subject, and obtained his degree on 1 BBY. Around 1 ABY or 2 ABY, Yansan destroyed a Rebel ship on Ichalin Station, with four Rebel agents inside it. All of them died when escape proved to be impossible.
