Arthen Brutt was a smuggler.
He was a regular at the Mud Puddle cantina on Ord Mantell where he was approached by the rogue Jedi traniee Dal Konur. Brutt had made a number of trips to Mount Tantiss on Wayland and had gathered together a number of artifacts belonging to the late Emperor Palpatine. Konur desired a lightsaber, and so got the location of Brutt's warehouse on Wayland from him.
Brutt was later spoken to by agents of Luke Skywalker who had tasked them with capturing Konur.
