Reist
this nightmare demon was controlled by Altin Wuho, via a lead-lined helmet and a forcefield bubble. Reist resented Wuho for holding him captive, but knew that Wuho would kill him if he didn't do his bidding. When Wuho was sent to capture Luke Skywalker in the Lapez System, he sent Reist ahead in a trackable capsule, leading him to Lapez 3. There, Reist tried to trap Luke by projecting images of the deaths of Han Solo, Leia Organa, and Luke himself. Luke was able to resist, and wounded Reist in a battle. Luke removed the lead helmet, freeing Reist from his captivity. This was able the time Wuho discovered them, but Reist died before he could exact revenge on him. However, Reist was able to tell Luke that Wuho was a droid, and that Luke could escape the planet with parts from his body. Luke dismantled Wuho and fled the planet.
